Kghorse, what area are you from? I'll be happy to recommend mine (I use the guy for almost 4 years already), but I believe he mostly goes to Montgomery/Howard/Carroll/Frederick counties. If you are interested PM me, please.
I was using Doug Ruch when I boarded in Montgomery County and now that I'm in Frederick County I'm with Sandy Ziegler. Pretty sure both are in the Equiery. I don't know what their prices are for a single horse - I've always gotten a group rate.
