Helping My Mum With The House Costs

I am 16 and I live with my mother. We are trying to fix up the house, and I want to do everything I can to help out, but we don't have enough funds for repairs and fixes, and there is no shortage of them! I would like to use the money to help out where I can, but also to invest in starting a small business so I can generate more money to help pay for it. Any donations are amazingly appreciated, I am trying every way to help out and I can't do it without support.

(The picture is a house that my mum showed me she wanted the garden to look like one day)

Thank you for even looking at this. Have a really good day :)
