I can't help with the processing, but here are a few words to help:
raw fleece is as it comes off the sheep.
Sorting, skirting, dagging, picking vm - all refer to ways to clean up the fleece before sending it off for further processing (no point in paying for muck and waste to go through the post)
scouring is washing.
Scoured fleece can be carded (fluffy) or combed (like well combed hair)
Once processed it can be tops, batts, roving, pencil roving and probably some more, depending on the proposed method of spinning and desired end product.
At various stages it can be dyed - as raw fleece, as tops etc, as spun yarn, or after it's knitted up, woven or felted.
How could I forget? There's New Lanark Mill
When I wanted to get my raw fleece processed there though they had no means to scour it, so it would have had to be sent down to Bradford, whose minimum quantity is something like 100 tonnes
Or you could scour it at home, but it's quite a job for more than about a dozen fleeces (from my little sheep - I wouldn't want to do even that many of yours Rosemary
) and you have to dispose of the wash water in an environmentally sound manner.
Things might have changed at New Lanark, as that was a few years ago, but if it's still Alan Barraclough who operates the mill he's very willing to discuss possibilities with you. It's a bit daft as they have a roaring river gushing down the weirs right on the doorstep
