Site Critique - Marketing Advice

I have just rebuilt my site at http://1adex.com.

I would appreciate any advice on design, layout, etc. As well as any
marketing advice. My thought it would be best marketed in printed
classified ads, but under what heading and what wording?

Also there is opportunity for people to partner with the site and have
"their own system". Comments on how this is structured would also be
appreciated.

Thanx

Mike H.
