I saw no one had replied so, figured id throw my thoughts out there

.
First off...welcome back to the game lol. With that being said - I think the first thing you'd want to consider is, how seriously are you taking it? Is this going to be a part time gig, weekend warrior gig or full time?
The next thing is, you'll want to be a bit more proactive. People tend to be a bit lazy ...an extra one or two clicks can make the difference between people engaging with you...or not. This post is actually a pretty good example of that. Rather than taking a couple of extra seconds to post a link to your facebook page, you just told people what to search for - which I did and it was easy to find, however if someone is say on their phone and saw this, just pressing the link to your page would be way easier than opening the facebook app, trying to remember your business name and then searching for it.
The proactive thing will hold true with your detailing as well. You'll need to constantly engage with people. By that I dont mean "Hey I'm detailing like my page and contact me!" lol, but I do mean being active with constant posts on your page, building followers (usually by being active in car groups and such helps a lot), share info on what you do (videos rather than written info can be very helpful) and just make yourself seen.
For your menu, It is short and simple enough to go through (where as many I see are overly complex and hard to understand). I'd suggest possibly bullet pointing whats included in each service (if facebooks format will allow that).
Your premium reads the following:
-Exterior wash includes cleaning and dressing of wheels, tires, glass -Dressing of plastic trim, rubber -Wipe down/vaccum interior, door jambs -Polish applied to exterior by DA buffer (removal of light to moderate defects, jewels paint) -Premium paste wax
You could perhaps change that by saying:
Exterior:
* Hand wash and full exterior detail (Including cleaning tires/rims and fender wells)
* Clay bar to remove bonded contaminates (such as sap, overspray fallout etc)
* Single Step machine polish to remove light to moderate paint defects and increase gloss
* Protective paste wax applied to paint, headlights, tail lights and chrome trim
Interior:
* Vacuum and wipe down of all interior surfaces
* Windows cleaned inside and out
* Door jambs cleaned
* NOTE: Full interior cleaning and detailing available as an optional upgrade
You're able to include quite a bit more info but make it easy to read still. This helps to build value in your service, without boring the reader.
Just my thoughts on what I saw, hope it helps some!
