I'm attaching a link to San Samuel Farm in Columbia. I apologize, it's in Spanish (I'm bi-lingual), however, it's a fascinating look at how they do AI.
The main narrator is a veterinarian. She makes mention of the fact that minis are different from biggies, in that their season is a little longer and their follicular development is different. You'll see their mini false vagina, a brief ultrasound clip, a n example of them collecting a stallion, and a BEAUTIFUL barn setup. Not to mention the drool worthy horses!! (They also don't believe in cross-breeding color patterns like we do in the U.S. It's strictly pinto->pinto, appaloosa->appaloosa.) Their contact info is at the end of the video. Since many of their breeding stallions are from the United States, I'd bet they have bilingual people on staff. You could contact them with questions you'd have about procedures, equipment suppliers and whatever else you might think op
As far as shipping semen, I think it depends on fresh vs. frozen. I don't believe distance is as much of an issue with frozen. Coordinating everything is going to be a bigger challenge.
Here's the link:
