You could try looking on the British journal of photography and Apogee websites.You don't say where you'll be based but if it's London then, you could start with KJP near Euston station, Teamwork in Foley St W1, Mr Cad in Windmill Rd, Croydon (bit of a trek but worth it) and of course Silverprint in Valentine place SE1 (near the Old Vic Theatre). All have websites btw.
