Barn management is always a well paid job. A lot of ranches and vacation resorts pay there managers very well. It does have a lot to do with business though. If you are looking for something more involved with horses, I would definitely recommend professional instruction. Earning certifications through different organizations and being affiliated with established equestrian centers will definitely up your salary.
Well I mean something like equine therapy (only for the horses not with the disabled) was what I was thinking. But it doesn't give a good salary so idk. But I get what you mean haha @adeline
I mean I wouldn't take the risk of being fed up with riding! It's going to be your job, and you won't rid the week-end because you won't have any pleasure because it's going to be your job! Do you get what I mean? :p
What do you mean "disgusted"? @adeline
I don't know if there's any job which pays a lot in the equestrian world... You should work a lot and I'm afraid of being "disgusted" on riding if it's really too much..
