Great Walk/Trot Potential

Misty is a large pony / small horse. A cute dapple gray mare, with beautiful black stockings, approximately 12 years old. Bought her as a beginner horse, and found she is not. She needs more work and I am not experienced enough to handle her training needs. Have been told by an experienced handler who worked with her for a week, that she would make a great walk / trot pony. Not sure of her breeding, but may be part arab, or part connemara. She is an easy keeper, good in the stall (no cribbing or kicking) , but she is exceptionally shy and nervous. Would also consider trade for a very well broke gelding of similar age and height. Give Misty a look - see, she is a very pretty girl. Vaccinations are current, not shod and to my knowledge has not been.
