Eventing/Dressage Prospect

I purchased Oliver as an eventing prospect; Due to school responsibilities I haven't had the time to create the show horse he has the potential to be. He needs an intermediate or experienced rider who is willing to work with him consistently. He can get excited around other horses as he's lived by himself for the past 2 years, but I have been trail riding with a neighbor and her mare, and he settles in nicely. He is responsive even while cantering down a long open trail with another horse. Behaves for vet and farrier, stands still for tacking up and mounting. He does crib, and he needs some work with his right lead. He will, however, do flying changes once cantering. I haven't done any jumping in a few months as my trainer moved to another state, but he did auto changes over fences as well.
