Propeller shops are good at it if you have a boat store ask there.
would it still be as strong at the weld? worried about it failing again. i think a new seatpost collar would give the best piece of mind. still not sure if she'll still want to buy this bike, even with a substantial price reduction.
it if were my bike I'd haggle to almost free and cut / install a new seatpost collar myself.
