Okay, price list is pretty simple.
4x5 (B&W, E6, C41) is $2.00 a sheet.
120 (B&W, E6, C41) is $5.00 a roll.
35mm (B&W, E6, C41) is $6.50 a roll.
For 35mm, develop+scan (no prints) is $12.00 for low resolution (4.5mb file) and $15.00 for high resolution (14mb file.) File sizes are approximations. YMMV.
Here is the kicker. They will only accept FedEx. You send and receive at your cost. So you have to fill out two "waybills" - one to get the package to them and one to get it back to you. That may or may not make things cost prohibitive unless you are doing volume orders. Again, YMMV.
When I get things developed here, they always come back clean and unscratched. Everything goes into sleeves, even uncut rolls of 35mm, which gets one long continuous sleeve (same with uncut 120.) 4x5 gets put in plastic slip covers. Push processing is free up to two stops, but I don't remember if that applies to B&W. I know E6, pretty sure C-41.
