I checked out your site and it looks pretty good to me. I think this is a product that has some real potential for profit. My one complaint about your site is that I have a pretty large monitor and all the info for your site was jammed to the left side of my screen. It took me forever to read and scroll down the whole homepage. There is a way to make your site adjust to the user's settings automatically which would fill in the whole screen. I am not personally sure how to do this but I do know that it is a fairly simple thing to do. I just think it would be more effective and easier to navigate.
