Paul,

If you are in the UK (and I can't remember but it seemed like you are) than you should heed Les's words and worry about a quality lab. If he can't find one, there probably isn't one.

However, since color film work is not at all the same as BW in terms of creativity and control, In my experience it is just about as cheap and with more consistencyk than you are able to accomplish at home to send the film to a lab.
