I do not see her as a hunter pony; based on her shoulder and on her breeding I'm guessing she'll move with some knee action and also may have trouble getting the striding.
I think what you have here is a solid all around prospect - something a kid could do 4 -H, Pony Club, local schooling shows, etc. If she shows good form over fences, possibly an event prospect.
Don't know about your part of the country, in my area, you'd have trouble selling her at all without more finishing as the market is so poor. Once she is stable at all three gaits, trail riding reliably and can jump a small course safely, she's be between $2500 - 4500.
