I live in an area with high business activity and as a uni student i think i found a way to make pocket money . I just need to ask some questions . Everyday i see many ads from businesses that are in shortage of certain products , from agricultural to anything you can imagine . What i want to do is to research local and foreign markets and find the best prices for these products , and then i will speak with both the businesses and the manufactures and arrange a transaction from which i ll have a small percentage . The problem is how can i protect my position ? Because they can easily get rid of me after the first transaction is there a way to tackle this?

PS: I have done many times something similar , i go to the countryside and buy products from local farmers and sell them to restaurants and some motels , but in those situation I buy the products , in the situation i described before i dont pull any money from my pocket.
