Before buying airplanes you might check with the club to see what their trainers are comfortable with using. If this is a one shot deal, the club may even own some trainer airplanes that you could use, which would let you use your money for fuel and incidentals, along with maybe hiring 2 or 3 of the club trainers to give you some full days of flying. That would be much better than buying planes and getting 2 hours total with instructors.
