Who turns old medium format B/W negatives into cyanotype suitable large format negatives?

I have some turn of the 19th century medium format negatives that I would like to print as cyanotypes. Do you know of anyone who will scan your medium format b/w negative and return to you a 5x7" negative with a density of 1.7, a large file of the adjusted scan, and your original negative?





Thanks.

Duggal would be a good bet.
