Whats the cheapest way to get the Auto only restriction (E restriction) off my CDL

Im in tampa area and trying to get the auto only restriction removed. But im in no position or intrest to pay in the realm of $3500 what trucking schools are quoting me, my current company wont let me test with one of our manuals and the only company that even offered isnt exactly an ideal running area and I dont wanna hop jobs just to get the training then bounce

Where im temp working ill never save that kinda money, im barely covering food/minimal savings to start another job

Any options? Im trying to get it done as cheap as possible no experience on a manual truck except a 5 speed M35 and I could barely pull that off.

3 of the current companies im looking at require manual
