PLEASE READ OUR REQUIREMENTS
We want to buy text links to our site, links which must be placed in pages with higher PR, at least PR1. We're not interested in links in pages without any PR, we're not interested in directory submissions, article submission etc. We want to pay only for links in good rated pages.
By page, we mean the exact page where this link is placed, not the homepage of that specific domain.
Of course, the links need to be permanent, without nofollow, without user-agent selection etc. We put the funds into an escrow account and release them only after we see the links in google's cache, so please do not attempt to do anything unfair.
Based on success of this project, much more work will follow. Try to estimate how many links and at what quality you can offer for $500. If you have better offers, they are welcome.
