This guy at Saint Paul Saddlery is amazing. I have gotten tack from him, and I am well pleased. He hand makes halters, bridles, harnesses, saddles, etc., any tack you can imagine. He can make it doubled leather or dingle, any color, any specifications you want. And his prices are amazing - I just bought a draft bridle, doubled leather with silver studs, and a beautiful pair of braided split reins - and it costed me 50 dollars. I believe he ships anywhere.
Last I heard, he has had to cut his hours and take a second job because he isn't getting enough business. I am fairly certain it's because he doesn't advertise, and his shop is a little hole in the wall place, not a huge shop. But I entirely vouch for him, and I beg that if you are looking to buy new tack or saddles, look here first!
