I am with the others, your prices are very low. You do not want to make it look like you will do anything for business, or make it feel that you are not very good.
Also, I noticed in the FAQ that in some places the grammar is incorrect.
Ill give an example: "The solution to this problem is a swirl remover to remove the actually C scratches that are in the painted surfaces, Instead of a polish. (Most polishes are filling in glazes not swirl removers)"
As you can see, the word "actually" does not fit the sentence. I would proof read your paragraphs, or have somebody do it for you.
On the webpage itself, I would axe the counter at the bottom, it feels very "AOL homepage". Also, everything is aligned on the dead left of the page with the content ending in the center. I have a display that is 1920 x 1200, so that could be the issue, but I would try to optimize it for every person looking at the page so it sits in the center.
