Paul - Ring Esler Crawford (Lisburn road below the "new" City Hospital entrance). I took my EPP 5x4s to him and got them back on a next-day service; so no need to unload. He ran a daily E6 line in 2007.
Since coming out here, I find it a bore to drive into Belfast even once, let alone on two successive days. I have sent stuff to The Darkroom UK in Cheltenham and have had clean and accurate results from them. They're at
www.the-darkroom.co.uk and you send them a cheque in advance (add 50p if you want your box back). They charge £2.50 per sheet and postage is free both ways. They appear to be accredited by both Kodak and Fuji.
Ring me at 92652234 if I can be of any help.
