If you rewrite this in English (lol) I might consider it.
Seriously though - this sounds a bit like an idea I had a while back but I am unsure because of the way you have written it.
Perhaps if you explain again - maybe using bullet-points to define the principles of the site - then I might be willing to discuss things with you.
Maybe...

Do you mean a guy/girl knows someone they want to fuck and gets the website to offer this said person money to fuck on camera on their behalf? If that makes sense?

Seen quite a few sites do the "pay money for sex" style of content but I'm pretty sure virtually all the girls are models. Realistically how many girls, not shooting porn already, would star in a porn movie which is going to be all over the net? Think you could struggle getting enough numbers in to be honest.

do you mean something like this?

I had a similar idea but I'm not gonna divulge it since I've still never heard of anyone doing it at all!!!
(Maybe there's a good reason for that though. Years of business experience has demonstrated to me through painful experience that sometimes the 'gap' that you find in the market is there because nobody actually wants a self-heating lawnmower! etc...
Anyway, good luck with it - personally I think if you're looking to do a site where people are offered cash for sex - out of the blue - has already been there, done it and pretty much set the bar quite high.
(I know most are actually models already but everything about the site is done just right to help you suspend your disbelief and get on with the fantasy.)
And, NO... I've never met the guy - I just know when things are done bloody-well right.
!grin!

I think you would be left with a lot of offended women in my opinion.
