Hi Jo,
Welcome to the boards! I'm not going to answer your question direct for two reasons. While I have taken shoes off before, Im sure one of the farriers on this site can tell you the correct way far better than I can.
Second is because I feel you have a bigger problem than getting the shoes off the horse if you truley can't find a farrier. The problem is not with the shoes but with the trimming. If you trim wrong you can really screw up the horse and may do permanent damage to the legs, therefore, making your horse worthless for anything other than eating grass. But if you have horses in your area you probably have some one who can trim and shoe. I would check with feed stores, some others in your area with horses, horse clubs such as 4-H or similar riding clubs, local fairs commetties or horse shows close by. You can also load your horse and haul to a farrier. Your horse well need trimmed every 6 to 8 weeks maybe 10 if your lucky. But the feet are one of the most important things on a horse and you have to take care of them to maintain a healthly horse.
Sorry I did not answer your question direct, I feel the problem is not with the shoes but getting the horse trimmed. Just my opinion.
Good luck,
Alan
