I would definitely ask...there is no reason not to.
Also, is thee an event center or other place that regularly has shows? You might see if they need help. Or...this one girl at our stable and in the "Pony Posse" (which I've mentioned in other posts) actually works off her pony's expenses and her show fees by going to other shows and setting up a tack cleaning booth and cleans saddles all day. If you do this, be sure to contact the show officials and get permission or find out about a booth.
Anyway, she is always talking about all the great horse people she met and all of the things she learned. Just a thought.
