My advice would be to get in contact with your local airport, find out what airlines have maintenance hangars there and try to make contact with them. Doesn't even have to be a big airport. There are lots of smaller airfields about the place, and these would probably be your best bet.
Good luck.
Edited to say that I'm just out of student diapers/nappies as well so I fully understand what you're going through trying to find experience! Keep at it though.
