You'll need oxy acetylene to get the metal hot enough. Just checked Harbor freight and they have an icy/acetylene torch for $170.00. You'll have to check locally about getting the gas bottles.
I can't really see what's wrong with the foot peg but if something's bent the torch will be useful. Fix the pedal first, then see what's wrong with the peg. It looks like it's just folded back which is what's supposed to happen in a crash. My guess would be that if anything's damaged it will be the perch that the peg is bolted to, and that it's probably just bent.
Take the pedal off when you heat it. If you have heat the perch, be careful and position pieces of steel sheet metal around the area to protect the engine. The perch can probably be carefully bent back into shape and won't need welding unless it's cracked or broken.
I do take work like that but I'm too far from NJ for it to be practical. I way overspent on my torch but I've never regretted buying it. I do a lot of brazing, too
