But you need to find a cheaper source.

Indeed :-)

Of course the obvious thing to do is hinge it at the bottom and let it
go down rather than up.

Not so obvious. There is a larger flap, lifting upwards, below the new
flap. See discussion here a couple of years ago. Plan is, the new
smaller flap (6 inches wide, two feet long) will flap up, hinged on the
left, allowing the existing flap (2 feet square) to lift, hinged on the
right.
