Conditionally rideable sidecar

Conditionally rideable sidecar - I am desperately looking for a good place for my large part-time pensioner.
As he can only be ridden to a limited extent (nerve cut on both sides in front), he would also do well as a lower-ranking horse in a small group.
If you have time, you can slowly train him up again and in the end he will be a great horse for riding out (lots of walk).
I'm slowly running out of money and I'm not doing him justice. He has been on a paddock with another horse for a year now and he just needs someone to look after him a bit more.
I hope you can help me and pass the word on. He is a really great one.
