0. Research the local market
Don't just research it,
know it. Inside and out, backwards and forwards.
Who is your competition? How long have they been open? What are their prices? How busy are they? How much money do they take a week? Where do they get their customers from? Where do they advertise?
What do they do that you don't? What will you be doing that they won't? How long will it take them to copy you, and can/will they do it better, cheaper and more effectively than you? Can they undercut you? Do they have agreements with local suppliers/shops/restaurants/etc that you will need to try and compete for?
Add up all your potential outgoings (including to factor in emergencies like equipment breaking down, any sickness on your part, all advertising and marketing, etc) and work out
to the penny how much you'll need to break even. Then work out how you'll be making this money and how you can absolutely, 100% guarantee that this will roll in week after week, month after month. Don't even
think about expanding until you are able to pay all your bills every month, and have at least a month's worth of payments saved up in case of emergencies.
Lastly, pay all your bills on time, in full,
every time. Your suppliers will be your best friends in the early months and you'll need all the help you can get.
Oh, and don't rely too much on market research. People will say
anything that'll get an annoying person with a clipboard out of their face.
