I had a similar idea pop into my head the other day, only it was to become a porn star.
I thought why not, if Ron Jeremy could do it...but while Ron and I share many similar physical attributes, there is something he has that I don't....experience.
Could I make money at it? Maybe in a certain fat hairy niche market.
Would I be able to compete with Ron? Probably not.
So while the idea sounds good today, stop to think that there are probably alot of folks out there that have had similar ideas and are much better at it than you.
Not to say you shouldn't try, just realize what you are up against.

Enjoy
