Who can manually develop a roll of 35mm film?

I was gardening and dug up a roll of 35mm film that is rusted and might not have anything inside. But it COULD and the local photo studios won’t touch it because it is “too dirty” and will gunk of their machines. Also, the spindle is too rusted to turn. So, this needs some good-old black-bag/spool TLC processing. Who can do this? I have to know what might be on this roll!
