don't even bother with the gym brother....you can't make money off of fat people unless its food...stick to the burgers and pizza...and although you can cake with a few franchises...its not easy...the main reason it isn't is because 1) you need at least 200-300k...and that's for the lower end franchises like subway and 2) you need to show a min. 1 million dollar equity for most franchises along with the best possible credit score/rating...
best thing but the hardest thing to do is come up with a small mom and pop food store idea and run with it....i know guys selling pizza and making 100-150k a year...no franchise fees, no fixed pricing, no territorial restrictions, no restrictions on how you advertise...
