If she is anywhere near a mounted police department tell her that getting them involved and holding desensitization clinics for riders and their horses (non-therapy) is a great fund raiser. Otherwise, if she will have access to a large arena (preferably covered due to weather) the same sort of obstacles that the cops use to desensitize their police horses can be put up to challenge rider and horse. It really is a money-maker for non-profits and fun, but it is a lot of work to put on.
