No particular suggestions for your area, but, to echo a point made by FFF the last time this came up, be sure to find an instructor who is a taildragger pilot, rather than a spamcan instructor who has checked out for tailwheel. You need someone with lots of direct experience of crosswind taxiing, wheelers, side slipping etc. Have fun doing the checkout.
PS: as you don't mind travelling, you could try White Waltham: ask for Ian Marshall or Bruce Hutton, although in my view WLAC charges more than it should for dual on its Supercub.
