Business start up

So, I have an opportunity to start up a business but can't for the life of me think of what to do?

What is there a market for?

What could I do from home? I have small children and I'd like to do something from home but I don't know what is in demand.

If you could start a small business what would you do?

I'm not artistic, nor can I bake/cook/sew..which is why I can't think what to do as all the other ladies I know have started businesses in cake making, hair & make up etc (all things I'm not good at) :(

I'm not looking to be a multi millionaire lol, just enough to pay the rent

Plsss helpppp (I knw its the wrong group but just wanted some ideas pls)
