A quick way to make money?

You seem to be in quite a tough situation. Could you try doing a paper round? you can get up to about $30 a week or something and you could always do more than one, and they're usually in the mornings or just on weekends so you wouldn't need to worry about balancing school work. Also recently I have taken to selling stuff on ebay. its easy to do and can make you quite a bit of money. Another thing that I am currently doing to make money is gardening for an elderly lady who advertised it locally. Its good because she pays quite well and I can go and work for her whenever I have free time, so that would also not interrupt school work. You could also think about babysitting, I have advertised babysitting and already have about 3 families that I babysit for, which makes me about $50 per week. I would also continue trying to sell some of your artwork, maybe on ebay? I'm sure it would go for something, as well as giving you practice. I hope I've helped and good luck with whatever you do!
