Analog film photography and cameras

Just out of interest do any of you develop film yourself?

I've a brand new dark room / wet room in central London empty quite often and I was wondering if people would be interested in renting/using it?

I've developed lots of black and white that I have never seen beyond negatives held up against a window – I'm dying to make some contact sheets but I've never done it so would need a hand.

Can you elaborate on your offer? What's the cost and could you give some guidance?
