I have a site that is currently bringing in around 20,000k views/month for a high priced service ($500-$40,000) My clients are mostly young and artsy type designers and musicians and just all around creative types. I have been considering switching to a free-version for some of the visitors that cannot afford my services but still obsessively try to beg me for them. As i am the only provider of this in-demand service, I think i would have a ridiculously high conversion rate for surveys and free signups in a content locker configuration in exchange for a freemium version of my service. I have done some math and i would need to make at least $20/per signup in order for my idea to make financial sense. My question is this...is this figure reasonable for some sort of survey or signup program and if so, can anyone recommend a good and most importantly trustworthy Network that will not shave or cheat and pays reliably? I am willing to use someones aff link as long as the conditions are met and its a stable payout.
