Service bureau for making digital negative from tif file

I'm interested in recommendations for service bureaus that can produce digital negatives from tif files prepared in Photoshop.

I'm in the New York metro area, but don't mind using a bureau outside my area if it's a good one.

Thank you!

P.S. I'm sure there are folks who would encourage me to produce my own digital negatives - no need to go there; i know all about that. Right now I just have a particular need for a service bureau.

Thanks again.

I've used this place ...
