Looking for References for HVAC technician in Little Rock Arkansas

I'm based in the Little Rock area. I've got my EPA 608 Universal certification, and I'm getting ready to apply for entry-level HVAC and electrician apprenticeship positions in Arkansas.

A lot of these applications ask for professional references, and since I'm just starting out in the trades, I don't have a deep work history to pull from yet. I'm trying to figure out the best way to line up solid references before I start applying.
