How to find linkbuilding/SEO firms for buying low cost text links, backlinks, blogposts, and other types of text links. Most ad networks are unable to sell more than 30% of the inventory they have , willing to offer the lowest rate for backlinks so that ad space will not be wasted.

maybe advertisers are lazy to contact you, you can try to add some automated Ad buying system for the advertiser so it is easy for him to buy an Ad.
One should also provide easy to find, detailed traffic statistics so advertiser knows what he is buying.
Then try to write forum posts and articles on your blog offering the advertisement. While writing these ad offers, think what advertisers are typing into the google search field when they want to buy an Ad similar to yours.
