As stated above, I'd be careful with the "not nice" reference. I've bought two horses from California and happen to know there are lots of nice people down there, lots with very reputable breeding program.
Did you offer references? Experiance with horses?
You can't expect to walk into someone's barn and let you play around with their horses without them taking care to make sure that a) you know what you're doing and are responsible and b) they have the resources and a need for you.
Horses are a huge investment and there isn't way I would let just anyone have free run of my barn.
Make some resumes, get some references, and go to a barn where you're best suited.
