Oh good luck! I have just taken on a new boy in very similar circumstances who I think is going to be a real find . I hope you're as lucky as I think I've been . Riding isn't everything , and that's the easiest thing to improve anyway . And who's to say the other two wont be as nervous ?
But riding is only a small part of owning a horse.I'd sooner a pony of mine went to someone who genuinely seemed to love them and had the right attitude than a super duper rider.
If it makes you feel better,we took on a lovely loan pony about 2 weeks ago.Until recently we kept our ponies at a private yard that we rented,lovely stables,spotlessly clean,good school ect.For various reasons,we have had to move them to my dad's farm,which is very much a working farm,dogs,cats,livestock,scrap metal,woodpile,tractors ect.We have no stables or school,just a paddock.I was dreading her site visit as I thought that it wouldn't be good enough and we'd be turned down due to lack of facilities ect.But she said it was exactly what she wanted for her pony,a farm home where he can be a proper pony and get used to all sorts of livestock and machinery.People will overlook a lot if they think you are the right person.
