Not sure my advice is the most traditional way of starting a business, but it has worked for me several times. Find a client/customer that will help fund your business. I've started three businesses like this, starting with $0 in the bank and just a dream. I've sold one of those businesses and continue operating the other two. Business plans, marketing plans, and all other plans are all great but I find that they are not the magic ingredient for success. I've started several successful businesses with no marketing/business plan but I had the most important thing - clients/customers for my product. After the dust settled, having a marketing/business plan is helpful for continued growth and sustainability for the company. Oh yeah besides hard work, sacrifices, and determination you will need a little luck. Good luck! Mitch
