Here's three bits to do before you start your business!
One of the best things you can do before starting is getting experience with an established trader. They'll give you the 'match day' experience of actually trading with paying customers, they'll teach you some of the tricks of the trade, fixes that they've come up with after years of making mistakes!
If you were starting in any industry, you would have done decent research, but because everyone cooks people don't feel the food industry is as hard as others. Wrong, it's harder! So do your research!
The money bit of a business is what separates it from being a hobby, as we've said before you can start a street food business on very little compared to other businesses but where to get it? How much do you need exactly?
