I meant pricey not because of the in-demand girls, just cause it's more or less a per minute rate. So you have 5 minutes of video, but you sell it as a 15 minute video with tons of fluff. Market it as a try-out video, with 5 minutes of the girl coming in, getting changed, "oh are u sure u can beat me? i dunno, i'm pretty tough, i don't think you're good enough for my website" etc. etc. Trash talk can be good if he were reasonably athletic and confident, and it didn't drag on for ages just to increase the price. Then some more fluff at the end.
Then when he does a second video with the girl, it's not just armwrestling, it's another 5 or so minutes of fluff, "i think i need to re-certify u, looks like u got weaker, u need to do the try-out again."
