Without seeing it, I'm going to assume it has a FEMA type 56 frame mounting base, the most common on fractional HP motors.
There are a zillion motors new and used with that frame 56 mounting pattern.
Ebay, Tractor Supply Corp, Amazon, etc.
Deal with the reset button before anything else. There are replacements available fro ereplacement parts or Ebay. They are a common item just slightly different mounting holes. If you feel so inclined, jump it out and see if the motor will fire up. It's a normally closed circuit, until it "breaks" then it's an open circuit. A light tap with a plastic mallet may free it up while it's unplugged. It may be defective it that doesn't work.
Some thermal reset buttons on Ebay:
