Don't give up. It may be a long road but as they say nothing good comes easy. Find a small shop and show your desire to learn and I will guarantee you will get picked up. Pay will be low but at the right shop your on hands training will be worth it. I have been in the business a long time and I still get to learn from my elders. What I am saying is the techs and installers will be more than excited to teach you. Hang in there and good luck!
