Do you have an "advertise here" on your site? If not you should, and if you do, what has been the response from potential advertisers? Have you contacted directly other sites that you see advertising on adwords that are related, yet allowed to advertise?
The only way to find out what your site is worth is to see what the market will bear in your niche.
