That's what we in the biz call a "non-committal dodge".
OP, the only thing that matters here is cash. I can tell you from experience that no matter how many people bumrush this chick and tell her they want to see her get tickled, that the odds of any of them actually forking over money for the resulting clip are slim to none. All this is going to leave you is $200 in the hole.
There are loads of foot models on Instagram that would be happy to work with you, so if you just feel like footing the bill for a "session" under the guise of a shoot, find someone whose arm you don't have to twist. You'll feel better about it in the long run. If you're serious about selling a clip, then get people to front the money to pay her before you shoot so no one gets left high and dry.
