Okie dokie, theres some groups on ravelry that might be useful then ,and your local spinners weavers and dyers guild will certainly be very useful
www.wsd.org.uk is the national and you will be able to find local ones from there. But seriously get yoursef a fleece ( they'll be shearing soon dont pay over £5 is my advice or free is better if you can find a local farmer) then look on the internet for how to skirt, scour and clean it then play around with the fibre and have fun
Also I'm no expert but feel free to get in touch
ps there was a whole piece that Red put together with regard scouring and washing on here somwhere. and remember theres no set ways how to do things
