Remember that WalMart started somewhere too.
1. Open a store, focus on the product, worker and customer, in that order!
2.Save! spend less then you need (my shoes are falling apart but I don't need new ones yet).
3.Invest in your business with your earnings, eventually build another store and repeat until you can hire someone to replace you.
4. Small business laws are difficult in U.S. but if you have the will you're going to be successful!
5. There is a free lawyer at every local town hall, go see him for advice!
good luck!
