You say "only 18" ... I hear "been a medieval adult for 4 years" 
I cooked up the five weavers explicitly hoping they'd be fun to take out on the town on adventures of this sort - by me or by any player. Gaston Lainnier certainly comes to mind as a shrewd bargainer, but any of them should hopefully have something fun to recommend them. (Pierre will be my companion character.) I can post precise character sheets soon; Blanche is already on the wiki.
