It takes more than a few weeks to learn how to massage, at least it does if you want to be able to actually help people with their muscular problems. You'd also have problems getting insurance unless you have some kind of recognised qualification- not that I ever needed my insurance in 8 years of massaging for a living, but IMO, if you're massaging professionally, you'd have to be crazy not to have it, given the litigous society we live in.
It's also not a great time to be getting into massage, it's mostly perceived as a luxury, which means it's one of the first things that people cut back on when they start to feel the pinch.
