Also have you thought about sticking up for your local skittles team, they normally pick you up and drop you off, so that would solve the transport.
i know my boy does it and earns about £10-12 per week, not a lot i know but put some pocket money and extra and he gets about £20-£25 a week
Also get out and wash cars, £5 a car, if you speak to some old people that cant do it them selfs, they normally get you to come round once a month, also windows as well, coupled with skittles or something, you will easy get £30-£40 per week
