Start at your local flying clubs. If you have good A&P skills you can leverage that quite easily these days since there seems to be a lack of good A&Ps coming up in the ranks. Go to your local airports and knock on doors and I'm sure you'll find someone willing to take you on and pay you in flight time. In fact I've known of companies that trained and promoted their A&P/pilots on jets. I wrenched my way through my instrument and commercial ratings.
The good thing about having your PPL already is that you can warm up the engine for compression checks/oil change by flying the thing around the patch or further, then post maintenance flights.
