If you are in the North-East, then Folkworks http://thesagegateshead.org/about-us/folkworks/ is the local agency promoting workshops and classes in folk and traditional music. I attended a couple of group workshops in their early days, one tutored by Ian Carr and the other by Martin Carthy. Found both very useful in different ways, but I guess I was already playing fairly complicated stuff by then and knew what I wanted to get from their lessons. When I was starting off, I was lucky enough to have a few friends at similar levels to compare and contrast progress with. I also learned some finger-picking from Brian Miller at Strathclyde University's Folk Club and found various musicians I was listening to had "tablature" books for their guitar accompaniments. There seemed to be many more guitar specialists around back then (Bert Jansch, John Renbourn, Stefan Grossman, Duck Baker, Leo Kottke, Davy Graham, John James, Archie Fisher, Hamish Imlach, Barbara Dickson, Gordon Giltrap, Martin Carthy, Nic Jones, Steve Tilston, ISB, John Martyn, John Fahey, Dave Goulder, Cyril Tawney), and seeing and hearing people play and watching their hands was one way of figuring techniques out. YouTube as suggested above makes huge amounts of tutorial material accessible, but you need to exercise some quality control, a lot of stuff that is up there is just plain wrong!

A year or two back a friend mentioned difficulty learning on a steel-strung guitar, but complained that all the nylon-strung guitars offered had the thick classical neck, which was awkward in other ways. Co-incidentally, a few weeks later I met somebody at a local session who was playing (very effectively) a narrow-necked nylon-strung guitar, a bit like the parlour guitars that were popular in the nineteenth century. It was an Ibanez AEG10E-NT Electro Acoustic Guitar like this one. I found one eventually second-hand and it's an interesting change from the twelve-string I usually play. Similar models are produced by other makers, Yamaha and Fender certainly and probably more.

Whatever you go ahead with, I would echo the recommendations above to get your guitar properly set up by someone who knows what they're doing. I struggled for years before figuring that out.
