She's got an Instagram and OnlyFans, why not contact her?
I said the same in my first post in here. Find out if she is at Manyvids, IWantClips, or Clips4Sale or you can even join her OnlyFans. Ask her to do a custom for you. When I wrote, "ask her to say your name" -- Ridiculous! you said. You apparently did not understand what I meant. You lay out the script that you want her to say and do. (Like you said, you can even be her "trainer" That was a good idea by the way.) Script it in such a way that she is talking to you and to you alone. A custom video will achieve the same premise and results and won't cost you five grand. You want a half hour video. Probably cost you $500.00 no more than $700.00. A fifteen minute video would probably cost you between $300.00 no more than $500.00. She would have to tell you how much a custom would cost.
I'd go the route of a custom video first. When you have a good rapport with her and she trusts you then approach her with your conditioning program idea. Having a good rapport means that she likes you. And you like her. Don't mention any amounts that you'd be offering her. It's much too early in the discussions for that.
This offer still stands. Anyone who knows Petra might inform her.
Investors? You're asking for someone (one) or others (many) to put up $5,000. Plus $5,000.00 put up by you. For a total of $10,000. Too much cash outlay. Bubb mentioned a business plan in the other thread. You need that. Here we have money being spent without a clear rate of return for those investors. Video sales? That's a dead market. Video production costs and distribution costs (in a proper supply chain) on those videos and then the storage of those videos will eat a way at their original investment. Try live streaming? How about places for customers to go and watch topless models. That means paying rent, lighting, heat and air conditioning, food and drink. Only place I know legally would be in Nevada. That means having business permits, licenses, etc. More expenses incurred without the investors seeing their first dime in profit. They need to get their principal back plus they have to make a reasonable percentage. Let's say ten to fifteen percent in the first year. Between seventeen to twenty percent in the remaining years in addition to their original investment. Can you guarantee that? That's highly unlikely.
Now, let's say however that you do come up with a workable business plan that covers everything and that you do get someone to put up the $5,000. Plus your investment of $5,000.00 making it the necessary $10,000.00 -- All to get Petra Verkaik into a conditioning program for the best shape she's been in since her Playboy days? That's not going to happen especially if you stay in the background as a silent partner. This is
your idea.
You need to take the initiative and you need to reach out to her or to her agent / representatives.
If you are serious, your best bet would be to reach out to her. If you have to deal with her representatives then deal with them. Find out who they are and make the connections.
Good luck.
