If you don't already know the basics I'm not sure why you have 3 wild ponies. ;) However, since you do and have asked for help I will say that Clinton Anderson's methods are very good as well as most of the clinicians who have media available. Your best bet is to find someone in your community who is calm, patient, and persistent but not cruel or loud. Watch them work and then ask for help with your ponies.
I have to agree with those that said get a trainer. Working with a green horse that has been handled is completely different than working with a 'wild' horse. If you push them too hard to go too fast, there is a very high probability that they will either injure themselves or you or both.
