I would recommend you change your tack. Like others have mentioned, your current website looks like one of the many internet scams - the 'success guaranteed' ones that end up selling you a lousy formatted PDF for $35. You don't want to associate your product with that kind of crap. Your first sales run might turn out half way decent, but if you make people feel like they're being scammed (even when they are not actually being scammed) they won't return and, more importantly, won't refer friends to your product. Even if your product solved my (non-existent) weight problem for me, I'd be hesitant to recommend it to a friend, because of how the site looks now. The first thing my friend is going to think when she sees the site is: "Jeesh! Jim sure has become gullable!" That's not how I like my friends to think about me...
For an example of a site that (in my opinion) does a very good job at presenting a software product, check out the
FogBugz website. It does a really good job of presenting the product (FogBugz) in a way that just exudes quality. Of course, the quality website has to be backed up by a quality product also...
