I think that you should build a better set of tour pages. Entice the user in a logical progression so that by the time they get to the price page they are ready to whip out the credit card. Using fuzzy full sized pics and very small thumbnail pics in your tour will not bring you the results you are looking for.
Personally, I would also choose a different background color. There are many studies that have been done on the affect of colors on consumers and the color you have chosen does not evoke anything on a subliminal level for me (That is just a personal opinion).
Hit me up via icq or email if I can be of any help. Kandi is the graphic artist in my organization and perhaps we can offer you some tips or you could contract with us to do some work for you. We have a list of excellent references available upon request.
