l do not have a bike, will eventually get one if l get into it further, so does anyone know where l could pay for lessons where they supply the bike?

l do not know about paying for lessons on someone elses bike as then the bike would not be set up to suit you specifically, but here are a couple of sites that will list tracks in your area.
