There are quite a few highly rated girls is Aberdeen who list outcalls and disabled clients in their profiles. Go to the search page and you can select them as search criteria. Obviously, they will charge for travelling time so it could get expensive, so choose carefully; make sure they have a lot of good feedback on AW and preferably here too.
Don't worry about legality issues. Nobody is going to care about a guy inviting a girl to visit him at home, and you're not breaking the law anyway.
