Hi there,
I think your efforts are comendable but you need to do some fine tuning if you really want to sell things from your site.
In honestly one of the fundamental things I felt lasking was structure and style. The pages looked clutered which makes it hard for your visitor to think cleraly.
I would try come up with a colour scheme that is less intrusive. The grey text was hard for me to read on the blue, but as much as anything I think working on mood colours and developing a style that really suits what you are selling would help.
Check out
www.w3schools.com for some tutorials on actually writing web pages. When you kow a bit more technical stuff it is much easier to get your pages to look the way you want them to.
Also if you can find it, check out a book called "The Non-Designers Design Book" by Robin Williams. I thnk she wrote a web design one as well as the one above is for print, but a lot of the basic theory is relevant to both print and web design...
Good luck
Tania
