Here's what to do. Pay them $5 to create a 5 min advert for their service, that displays different styles of technical proficiency, and showcases what they can offer. But with 2 stipulations.
1) It must be in YOUR name, and 2) they must say that its $20 per 5 min video.
Then use the vid to advertise their services as if they were your own, and for every $20 job you get in, pass it over to them to do for $5 and pocket the extra $15 for yourself...
