Modern aeroplanes don't often have that sort of payload - and those that do, probably aren't rentable.
I suspect that what you probably want is a share in an older 4-seater. I certainly know of a share going at Booker that'll tick your boxes (if you don't mind doing a tailwheel conversion), but nearer to home you might have a look at e.g. Popham.
Something like a Rallye, 182, 180, PA32 - or possibly some of the more obscure vintage types might do it. But hiring?, I doubt you'll find much.
