Yes, I've tried craigslist. There aren't too many people in my area that deal specifically with bucking. Do you know anyone who would be willing to travel? Or I'd even consider sending my mare off for training if it was the right fit and I knew something was going to get done.
The trouble is finding a trainer brave enough to get on her and fix the issue (I've been through 2 now...the first she threw off and scared away and the second told me she needs someone who deals with bucking all the time...she's a college equestrian team coach...she said she's never been on a horse where she actually feels in danger but she does on my mare). She just needs someone who deals with this stuff all the time to point me in the right direction and I can take it from there.
This fellow is in eastern NY but he will work with your horse and do a good job. He is a good trainer but you would have to send your horse to him since Rochester is about 4 hours west of his location.
