Hi!
I just sent a purse in for restoration. The ebay advertisement said "Excellent Condition" But I think it's more of a "Very Good Condition". Normally, it takes a few days to get oil stains out from the leather. Anywhere from 1 week light usage to 4-6 weeks for heavy usage. I am from Toronto, Canada. I used LoveYourPurse in Toronto and other one that is in Lewiston, NY, LovinMyBag.
My heavily used one is like buying a new purse $1200 - Restoration which included new lining, new zipper tabs, piping repair etc. Moderate Usage: Oil Stained handles start at $225

In hind sight, I think I would just restore the purse myself unless I needed a new liner or dye or deep stain removal.
Hope this helps.
