No idea - I don't know him Do you know anyone who has had lessons with him or knows him? Ask them if they think he's be a good teacher

Phone him and have a chat about it - tell him what you want to be able to play and ask him how he'd get you there. And ask him for references of other students so you can find out what they think of him as a teacher. If he's decent he should be more than happy to give you references, and will probably want to find out a bit about you and where you want to go with guitar if he's going to be teaching you.

If you're happy after that, go for it, but just book the introductory lesson to start with and see if you think you'll get on with him.
