I did something similar right after I graduated high school. It's pretty much what cougarclaws said; speaker guys like to work parking lots and fast food places. Magazine people like to work dorms and apartments. The meat guys will work whatever. It's about as close to a pure hustle as one can get.
All are essentially the same setup; get an office/warehouse, preferably in an office park and run ads in the papers to attract people with little experience or otherwise qualified to do anything else besides stock groceries or work a cash register. When you bring in new people, you have to work them just as hard as you have them work people in the street. Make them feel really bad about giving up. Turnover is obviously high, but if you can keep several on, they will cover your cost.
A lot of groups will travel to keep from burning out their home territory. It takes a tremendous amount of energy to keep up morale because everyone is constantly telling you GTFO and getting kicked out of buildings by security. This is where someone will either quit, start getting wasted all the time to deal with it, or just turn shady.
No matter what city I was in, I always had a way of finding the 'massage parlors.' Catch them on a good night and you can bring in some serious cash. I was surprised the first time I went in one and saw they took credit cards (this was about 15 yrs ago). One place I remember, I'd sit in the office and hang out with the manager and a couple of the girls. He had a whiteboard with a big list of rules (don't be late, etc.) and how much they would get fined if they broke one. It was kinda odd being in the middle of a conversation with someone and they say, "hold up, I gotta go suck this guy's dick, be back in 10 minutes."
I ended up quitting when I realized the whole cash every day thing was probably not the best arrangement for me at the time, because it didn't go well with the liquor store every night thing.
