I found First Tutors via search engine and quickly found the profile of a Physics tutor who lives walking distance away. The profile included mention of strong interest in playing guitar, which while irrelevant to Physics lessons, told me all I needed to know about whether my son would connect with this person. The only hiccup was that for the first couple of exchanges the tutor and I both received email notifications that we had a message waiting, but those notifications stopped and we both let days go by not aware the other had replied until we eventually logged in to chase up.
