Yes, I know control doesn't use cards, I suggested them so he can take a look at it and maybe, just maybe, add it in his repertoire - plus, it's not that hard to do.
Gaffs? I don't think using gaffs early in your career is a good idea, a month of card handling, I assume that less than half of that is placed on street performances, once you test the streets, specs would try their best to check the pack specially if a gaff is used, aside from double backers (well, that's in my case, I live in asia btw, don't know about other places, people react differently to magic).
To tell you the truth, those advices of mine may be hard, but I'm not telling him to learn them now, of course, if there's a sleight/move there that's a bit difficult to do, then its his responsibility to search some moves that would replace a specific sleight.
I won't suggest crash course and the likes, why? It may be simple sleights, but those stuff may be learned from youtube, I'm thinking about saving. And he can always try to find magicians in his place that'll take him as an apprentice, that's what I did, and I saved a lot.
ps, to thread starter,
try the Encyclopedia of Card Sleights (not sure about the title), it has, I think, 8 volumes, which will teach you some stuff. I don't know where to find it though.
