I also recommend Barefoothorse girl....if she can't do it, she will know some one who can.
I get the EQ barefoot performance trim on my 3 beasts, and I highly recommend it. You also have to offer a more natural way of living to the horse to get the maximum from this trim. Just to short form a bit.. out 24/7 with access to hay and water. Hay placed around so they have to graze is preferable, varing footing.. crushed rock/gravel to grassy areas.. the more different terrians the better. Feeding as natural as possible.. most horses only need hay, water, and minerals.
Good luck finding a trimmmer... your horses will be so happy you did.
