Anyone can give me a hint how can I start this project?

Hello warriors,

I have a project for which is essential first step to contact and get on board a number of about 40 cam girls from any "sex cams" type site.

I want to accomplish this just by sending to such prospects a very short 15-20 word message, with a link in it (practically I propose them to read about a way they can make a substantial monthly extra income with very little time investment on their part, and very-very easy to do in their situation).

Now the problem seems to be that on all the sites I have reviewed you can send PM-s to the performing cam-girls, or you can email them, or you can post comments on their personal profile page, which also would be good enough to me (some sites have this feature) ONLY if you are a paid member of that site. NO free registered members were allowed anywhere on such sites to get in contact through messages, email, etc. with these girls.

Any one of you have any idea how can I pull this off without paying for membership on such a site? Any site will do, just not some starter site, has to be a bit established.
Thanks in advance.

PS:
After I'll get my needed number of participating cam girls for my project, I plan to share participation in this project with at least 120 warriorforum members too - they will be able to make a still nice enough extra monthly income of $700 very easy.
