Thinking of having my own business

I guess it's time for me to invest in a business. I am doing good with work and I am hoping that it will continue in the months to come. One hit business now is the food cart. These carts are usually found in malls , near school areas, commercial buildings and sometimes you can even rent it out on birthday parties. I plan to start in determining how much capital would I need and a I need to look for a feasible location as well. A friend told me that equipment leasing is available online so I guess that would be easier and more convenient. Hopefully I can start planning the business soon, I need extra income for our growing family.
