Personally I do not list any specific products on my website, unless it is CQuartz or something like that. There is no point IMO. Just like my uncle, also my mechanic, doesn't tell me what after market wheel bearing he just put on my car. 1) makes no difference to me 2) how am I supposed to know the difference between aftermarket bearing A and bearing B?
I took a look at your website and I have a few thoughts. The first one is that I would switch the order of your packages. People instinctively think the top is the cheapest and prices go up as you scroll down. My next point has to do with prices...
Well I woke up a tad early for my morning detail, so I decided to do some research into your area. Obviously you know your area better than I but to me when I hear Cambria, PA I don't really attribute it to $$$. I checked out the US Census for Cambria and here is what I think is most important. Assuming the majority of your clientele base is men that are over 18 and above the poverty line that leaves you with ~48,000 people who are your core demographic. However the average income in Cambria is about $42,000 which equates to about $20 per hour.
You charge about $400 for an entire car, based on my times that is about 8 hours or $50 per hour. That is about half the weekly wage of the average Cambria citizen, that is a lot of money to spend on a detail. Ultimately your market sets your prices. Going forward I would remove all your prices from your website and organize your packages from cheapest to most expensive. If people want their car detailed, they will be forced to contact you. When they do contact you ask them what they want done, then state your price. No one wants to feel like they are cheap or poor, it is a lot harder to say "no that is too expensive" over the phone then it is to click out of a webpage.
This is essentially the model I used to work out my prices and what not. The only difference is my market size, about 2000% larger than yours and there is a higher average income which drives my prices up.
Edit: Also I would look into expanding into Pitt. I realize it is far. But if you manage to get a couple of cars scheduled for your more expensive details you could drive up there for a few days and do the cars then. Worst case scenario is that your break even, but the exposure and photos for your website could offset that in the long run.
Best of luck buddy.
