You might want to have a look at
Text Link Ads as they will find static ads for your site & calculate the value based on various things such as traffic, theme, ad position, and link popularity.
If you don't want to go ahead with them, submit your site anyway as they will then let you know how much each link is worth, so you can get an idea of the going rate. For example, the going rate for my blog is $15 per month for each link. My traffic isn't high though - if your site is a high traffic one,
Text Link Ads will assess your going rate to be much higher.
