Natural horsemanship/track system temporary loan home wanted

Hello everybody, Just putting the feelers out initially as this has been a very difficult decision to make and finding the right home is more important to me than anything for these guys.
Are there any natural horsemanship and/or track system homes in the highlands that would take on my horse and two ponies temporarily on loan for a year?
They are currently in Orkney so location within the highlands is not hugely important.
One TB gelding, Fell mare and Shetland mare. All mid teens to mid twenties so just looking for a home that they can maybe join someone else’s herd and chill out for a year.
No health issues in the bigger two , some laminitis in the spring/summer and arthritis in the old lady Shetland.
I have always managed to manage it ok and happy to talk this through fully with new home.
All of these guys have had difficult experiences in life so just looking for a chilled place for them for the next year.
I have managed to keep them through some really difficult periods in my own life but I feel this is the sensible decision to make now. I think the absolute world of them, particularly the fell mare who I’ve had since I was 18.
I would like to be able to visit them every now and again and also would greatly appreciate being kept in touch on how they are doing.
I’m more than happy to cover transport down & put some money towards their upkeep.
I would be looking to get a contract put in place.
