Do bear in mind that starting a business from home is not an instant way of earning money.
First you need something that you can "sell".
You need to set yourself up to carry on the business. some things need gualifications, some planning permission, and everything needs cash to start the ball rolling.
Then you need to publicise it, which will take either more cash or a lot of legging it round doors and notice boards with flyers, or both.
when the customers strt appearing - in dribs and drabs, usually at inconvenient times - you can't ease up on the publicity. If they thought you were good, they might tell their friends, but only one in a hundred of thoe friends will become a new customer. You have to keep plugging.
You will also have to keep regular and accurate accounts, because HMC will be after you for tax at some point, and if you have no records they will assuime that you have been coining it in.
Can you do all that?
