Trying to earn money for sports

Hi, My son is 9 and currently plays on a competitive hockey team. We have fallen on some harder times and he is really hoping to work and earn some money to pay for his couple away tournaments as he’d prefer that I be able to attend with him rather than going with another teammate. He is happy to do gardening, leaf clean up, mowing, snow shoveling etc. I will also be helping with him. Please message if you have anything you think we may be able to help out with.
