OK, you've got some great input so far. I'll not touch on SEO or website optimization. But I want to throw some other ideas out there just from reading your site.
First page:
Lots of photos that really don't mean anything. Reflection photos don't mean anything to people that have no idea what they are. Providing a 50/50 is useful, just that the one on the left side is in the wrong place. Needs to be in another place that shows the work. (all 50/50's together)
Do NOT show a bucket full of brushes! Same thing with the detailing supplies. All the photos on that line, except the pickup just don't work. Especially the car with mis-matched wheels.
Interior cleaning:
Show the work. Maybe a 50/50 clean/dirty seat or carpet. Shot a closeup shot of how you get into cracks and crevices, maybe with a detailing brush, or a steam cleaner in action. Get DOWN into a closeup shot and show how clean it is!
The Mentality:
Needs rewording.
First line is OK, understanding products needs a different description. Remove the double PERIODS. Last line shows negativity of your knowledge. You already HAVE confidence. I'd think about just rewording the entire paragraph.
Paint Correction:
I'd change the second line. Maybe something more towards "No matter the condition of your paint, we offer packages that result in a flawless finish." Maybe something as to what paint correction is, and why it's needed.
If you could change the bottom line on that page to a positive review from a customer. ????
The "About" page just doesn't work. Aside from the story line (that customers just don't want, or NEED to know) grammer and typos are in the first and second and third paragraph. I just read the first paragraph to my wife and before I got to "After a few months" she said TMI.
You don't want to lose your potential customer with your history since grade school.
Services:
Again, grammatical errors in the first line. And continue all the way through.
Focus on WHAT your products are, what your process is, and how you get there. Look at what the others in your area are doing (via their websites) and then describe your method. You can focus on what YOU are doing that perhaps others do not do. Just do NOT say that XYZ doesn't do this but I do.
Is "Supreme Wash" a wash, or is it a wash and wax? Narrow the service down to what it is. Put down to more like appx 3 hours and go from there. Include a spray wax with the wash. (
Let them know that it is a wash and wax. After all, your competition may not be doing both at this price point.)
If you want a profitible add on over and above the "Supreme Wash & Wax", I'd consider adding a Polymer Sealant. Then describe durability as 3~4 months, or 4~6 months.... whatever. Just as long as they
know that a standard "wax" product is a 4~6 week option.
"wanting to sprucin' " just dosn't work.
It also isn't about "customers" but about "vehicles". Talk about what you can do for a VEHICLE. The first line could be something more like:
Perfect for vehicles that are driven daily to add a quick deep shine with added protection.
Full Exterior - 2 step
You NEVER want to tell a customer that you are GOING to put haze and micro scratches in their paint! Why would they want to bring a vehicle to you that they already think nothing is wrong with only to be told that in the process of polishing that you might not get it right the first time, you are going to put haze and scratches in it, and that you will keep working it though until you make them go away.

That can have them thinking if they don't have you do a 2-step that ALL your 1-step methods will scratch their vehicles paint.
Leather Rejuvenation:
Not bad, but leather doesn't automatically get shiny/glossy, film covered and have cracks after just a "few months". Perhaps lean more towards WHY you want to protect your
valuable leather interior.
Then you can go to what your product does, and what makes it so special. ????
Interior Deep Cleaning:
Again, this is going towards a thinking that says, "Hey, if your vehicle is filthy this is what you need."
Spelling of "than" rather than "then"
I understand what you are trying to say, but the customer may not think their vehicle is in need of this service. I'd maybe start that sentence with "Whether your vehicle is just lightly used, or you are the "go to" for your local youth soccer team, our Interior Deep Cleaning is for you." Then go into how you have experience, and can remove..... x x x x x x and x.
Also talk about not just stain removal but the entire interior, using quality products, adding value to the vehicle, providing stain resistance and UV protection. Etc.
Headlight Restoration:
I wouldn't discount my "Wash & Wax" services with the headlight service. I may however discount the headlight service
if it's added TO the wash and wax.
I'd drop Convertible Top all together. (
But that's just me.) If a customer has it, then you can do it. Remember, most don't.
Where you want to mention all your other add on's is in a single place within your menu.
The Portfolio
Now THAT is what I'm talking about with the up close shots!
If you can just take a
wide angle shot of an interior to add to your Interior overlay that's all you need there. The bigger the car, and the lighter the interior, the better!
Finally, the Contact page.
Don't tell your prospective customer, Hey, if you call and you don't get an answer, well I'm just one guy. I do it all, and when I get time I'll call you back.
When a customer sees something like "
I usually get back to missed calls within 24 hours" they will instantly think, Well great... I may wait a
day for this guy, and then again,
he may not call at all! That's not cool, brother.
Your prospective customers need to feel as if you are the ONLY person they EVER need to call. When your phone rings, you answer it. If you're hip deep into a cleaning job at the time, make sure you check your phone every 15 minutes or so. NEVER make a customer wait more than a few minutes for a call back, EVER!
Even when I was just one truck with my towing business I kept a phone with me. As soon as I started picking up dealerships and insurance companies I had an answering service with a Live Voice on the other end. When people called they didn't know it was an answering service. Move to multiple trucks and the answering service stayed in place whenever I wasn't at the phone. You just don't want (in that business) for someone that's stuck on the side of the road to have to leave a message not knowing what was happening, or when someone was going to call them back. They would always get a "confirmation" call just a few minutes later to schedule the tow.
Finally, Your customers also don't need to see your car packed full of stuff. (
Now they know the earlier photo with the mismatched wheels is your car as well.) The car looks nice, the black and white wheels not so much. Take a shot from the other side.
Hope this helps, just trying to help you gain a perspective from the customers vantage point.
