I don't know of any darkroom facilities for hire, but here are a couple of other answers:
- TMax is easy to find, at least in Bangkok, ISO 100 as well as 400. Tri-X is available too, but harder to find. I usually buy at Foto Hobby, Silom Center, But Camera Collection at Charn Issara (Rama IV) (
www.cameracollection.net) and Fotofile at MBK would also be able to help you. Camera Collection also does darkroom work, including b&w. I've never tried them, but the guy who's running the shop is a photographer and seems reliable. I see more and more Ilford films around btw. Except for Tri-X, which is rather unique and cannot really be replaced by anything, I would give that a try as well.
- The colour tinge is a well known problem. My safest bet for b&w prints is IQ Lab (
www.iqlab.co.th), but I haven't used them in a while, since I mostly print myself nowadays.
