Would anybody give me any advice on how to improve this site / service.

I will review a site of yours in return.

too many things going on at once, unless you add more images and less text, you aren't going to get much visitors that will become interested.

I agree. Also keep all the links in one place (or two if you do one sidebar and one head bar). Try to keep the color scheme to 3 or less colors. Background color, Link bar color, then a different color for the content section titles. If you have a border on the content sections then let the background color of them be the same as the sites background color.
