There is a lot of information on line. Sites like this where you can talk to others has been a tremendous help to me. I have made lots of mistakes and then made new mistakes but I keep learning. I am struggling with new issues every day. If you get out and talk to vendors many of them will help you. Before I began my vending cart and after 1 year of research I went out and spoke to some vendors. Many vendors felt I would be a future competitor and were not friendly however one vendor was very nice and let me help them for the afternoon so that I could learn. We keep in touch and still help each other, we are located in different cities. It has been more help than all my research. So if it is possible get out and find vendors face to face who are working a business similar to what you would like to own and talk to them.
