I tried another recent job posting, went for a taster/trial session and just didn't get any further shifts e.g. No time to look at work schedule or canceled in the morning when I was supposed to come in.
Have you considered buying bikes, repairing them and selling on? Get to do the spannering on your own terms and potentially more money. I did this part time to get cash together to buy my flat. Worked out at a very good hourly rate if you look at it that way
