you re not going to make much money selling FROM THE STORE, since it is, as you said a low income drug infested area, but yoy stantto make great profit if you sell stauff on EBAY, as you said...Just be careful, what you buy...Stick to gold, jewelery, muzikal instruments, higher end electronics, PC, cameras, phones, and expensive tools...DO NOT BUY ANYTHING ELSE!!!!, Or you'll have hard time selling he stuff back...You also have to become a scrupulous owner, paying 10-15% of the resale value of stuff, since you going to be waiting on average 2+months to get the turnaround on your money...
Another thing....$8,000 should buy you a majority stake in this business, since you probably not going to see the return on the merch(you said $20,000?) Movies, and little stuff is a hassle to try and get rid...I would not count that crap as anything towards a value of the business...You also have to account rent, bills, taxes, shipping, salaries, and cash for purchasing power,,,I would bring in a lawyer and demand 60% of the profits if u invest your $8,000, JMO, BOL
