If you are ok with single seat I think there are some very inexpensive PFA shares in your part of the world. Alternatively you could find a Jodel or similar, which gives you two seats. Up in the midlands there are Jodel shares for around £3k (for 1/6th) with £25 per month and £25 per hour ish. I would assume in your area it will be more but it will still be very low compard to renting a 172/PA28.
