WB makes a great point..it doesnt have to be flashy, effective , practical and consistent,,,,much more important...
Tanning salons are still not bad...it helps if you have a spouse though to work it...I would be afraid to put anymore than half my net liquid cash into anything...unfortunately I got started late, like a dumbass I wanted to be a pro soccer player and wasted my early adult years...to me its not so much about making a TON of cash, its working for YOURSELF and not having to answer to some schmuck boss...thats my motivation...its a nice feeling too....
