Resume writing won't help much. Every operator I have spoken to, and that is just about everyone, has said the same thing. "Sorry we don't need any more staff". It's not about qualifications or attitude, or how much Mummy and Daddy can afford, it's simply there is no movement in the industry. If nobody at the top is hiring, nobody at the bottom is moving.
The head down bum up advice is great, but I can't even score a crap job let alone a good one. It's been over 2 years since my last paid (flying) work and the answer stays the same. "Even if you'd do it for free I can't take the work off my guys". I totally understand that, nor should you. So where does that leave everyone else?
I looked into glider towing as well, I was basically told you have to be the son of the guy already doing it, and wait for Dad to die.
