Applied at MJ Tanker Lines for Unknown

I'm currently on the job hunt for tanker driving roles in the San Gabriel Valley. I have nearly four years of driving experience and just recently obtained my double/triples, tanker, and hazmat endorsements. However, I'm struggling to find companies willing to hire me since I lack experience specifically in doubles and tankers. I applied to MJ Tanker Lines but unfortunately got turned down. I've also submitted applications to Airgas for a bulk driver position and Elite Fuel Lines. I'm looking for any recommendations for companies that are willing to hire and provide training for someone in my situation, ideally with overtime opportunities after 8 hours.
