Making money out of my domains

Hello all, I`m sure this question has been asked before, but here goes.

I have a few domain names that i dont really do anything with mainly because i dont have the knowledge to do so,

The names that I have developed are all on the first page of google after some basic seo and adding links to the free places and also a couple of blog adds ect.

I have no experience in web design only altering templates in dreamweaver and to be honest they dont look that good compaired to the competition,

I have noticed sites on the net that are shops but they link to other companys I use an amazon affiliate in a couple of my sites but they dont look the part and i dont make much from them either (maybe due to visitors but in my mind its main due to the look of the sites.

What is the best way to make a affiliate shop?

Is there a site that offers ready made affilate templates that i can add actual content to and do seo, I found www.associate-o-matic.com which looks ok for amazon but just wondered if there are any others out there so i can start making a little money out of my domains?

thanks for any advice
