"He who marches out of step hears another drum." ~ Ken Kesey
as somebody who has been starting business for last 20 years, here's what I've learned (rather painfully for the most part).short version:FIND SALES FIRST! find somebody, or preferably multiple ppl that will buy your product first. If you can't find somebody to buy it now, what makes you think you'll be able to find them later after you've already made the time and money investment to start the business? Out of handful of companies I started or was involved with, the ones that had sales before opening the doors were the ones that did best. long version:worry about the business side before the other stuff you are asking. You'll need to develop a business plan and that will answer the questions you are asking. Figure out the market share, market size, investment requirements, cash flow, SWOT (strength, weakness, opportunity, threat) and so on. Sign up for a class that will help you develop your business plan. 'not sure where you are located, but here in US there are workshops offered everywhere that will help you with it. Pay $200-$300 for a 6-12 week class and by the time you are done you'll have a complete business plan. Having one makes it 10 times more likely that you will succeed.pierre
