Equipment operator certification training?

I’m an operator with my company (teleskid and telehandler) but they don’t certify. I work 10 hour days 4-6 days a week so I need weekend classes or online. I’ve looked around but all I can find are commercial schools and they’re all weekdays. I’d also love to train/certify with larger equipment.

It’s a longshot, but if anyone has advice or knows where I can look, I’d appreciate it!
