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.

For the hobbyist they may have a value but a commercial shop would
probably have no use for them because of them being undersized from the
sharpening. Unless you can hold the size to within a tenth or two you
must reprogram the cutter comp for each end mill as compared to using
new end mills that are right on size.

The small 1/4 in end mills are not worth that much. Larger ones over
3/4 inch start to become economical to sharpen because of the higher
replacement cost.

Maybe that's why they are dumping 400 lbs of end mills.
