Someone is offering me a lot of appx. 300 lbs of used HSS endmills,
which are neatly sorted by size and need resharpening, for $75.

Let's say that I had an end mill sharpener like a Darex V90 or
whatever. Realistically, how long does it take to resharpen an end
mill (I would hire someone) and how much can I get per dozen of
"professionally" sharpened end mills, say in 1/4" size.
