Good mornin'! I am posting this publically for you Wildcrafter in case anyone else is interested. I called Gulf Island Spinning Mills for you this morning. Their turnaround time is "fairly quick" she tells me, usually within 2 weeks for washing and carding. Their price lists are on their website, so I will put it here again if anyone is interested. They sure are nice folks there!
I haven't used them for carding or spinning Sarita, but I have bought their finished wool at craft fairs and knitted it up. It was beautiful to work with and flawless, and their colors are to dye for! Sorry, bad pun!
