I agree with the polishing step. Clarify if it is a one/two/multistep polishing and correction process.
People are more than willing if you
educate them. My Level 1 treatment is $200. Not including interior.
I see nothing wrong with them. Just remember that in the beginning, higher prices wont attract the masses until you have a reputation (take a year+ till you make a profit tbh). I dont have it advertised on my site, but I actually offer a monthly contract for $100 - basic wash/dry/vacuum/wipe down. This is very popular to keep your customers coming. Cut specials for the loyal one, this goes a long way.
My only advice is to maybe make it clearer to scroll down on the front page. I spent 2-3 minutes clicking on everything until I realized to scroll down.
I would suggest removing the logos of the companies too. If you are going to be more chic/high-end, KISS! (keep it simple simon)
Advertising the products you use isn't always the best way attract people. To the non-pro, swissvax and simoniz are the same. If you are going to advertise the products you use, give a quick little synopsis/history of the company. Dont force people to look and do research for themselves.
