You could try Panshanger Airfield (North London Flying School), near Welwyn Garden City.
I wouldnt pay anything up front and only pay as you go. Flying isnt cheap, and the money saved will be negligable and the money lost if they go bust will be devastating. If anyone is any way a bit 'funny' about this, give them a wide berth.
And you will get over your bond with your instructor. If you do a PPL over a course of a year or so, you might end up with 2 or 3 instructors and many different aircraft (most people usually have an affinity for one of the club fleet), but thats just how it goes...
