Update............
After emailing more aroung 150 girls
Still not found a girl up for this, apart from 3 girls that are over 45 and Miss A Squires, but dont want to be paying 200 an hour .
So thats it........
I'v well and truly given up
Well you should probably give up then, if you're having so much trouble. I've filmed girls who offer it on their profile, filmed girls who don't offer it as an option (just ask them when you see them, it's much harder to say no to someone's face than it is over an email). I've only ever put one RB on for filming, and I had 15+ bids including girls who don't offer it on their likes list.
I've had success filming girls who are independent and agency escorts. Over a 6 month period I've recorded over 10 different girls, and that's just in the North West area. It's really easy.
Or you can get yourself a regular WG and build up some trust.
The more I think about it, I think you should just give up punting altogether
