I always have Equstreamz on mine - magnetic bands which I highly rate. They can be used for turnout as well as stabling. I have a 10% off code if you want to pm me x
I would post in the tack room as it gets more people looking, but I would post looking for a part loan/share on local facebook pages. You will have more luck than at riding schools and it will give you a step up from riding school horses!
Good luck
