Why not rent out your chest like this guy.
He gets $20 to write your message on his chest and post the pic on his website. Female breasts are available for rental at $2K per pair (though that would be harder to read).
Sell your chest every 10 minutes at only $20 each and you'll make $20,160 per week, and over $1,000,000 per year. Rent out several people's chests (think outsourcing oversees) and you can multiply that many times over. Pretty soon you'll be talking about real money.
