We will, we will, walk you

Sorry for the dumb title, but I hope it got me some attention. My dog Pit is pretty scared of dogs he doesn't know, but is very sociable when he gets to know them. I'm looking for someone who is prepared to be a little patient with him and walk our dogs together in parallel for a while so Pit can get used to you and your dog. I want him to learn that strange new dogs are potentially friends. This would be of great help to me so I'm prepared to be flexible on the location.
