Cabair does exactly what you are asking about, so long as the aircraft is on Public CofA, & is of a type that either Cabair presently operates, or a type for which there would be sufficient demand from hirers.
A PA28 Warrior or Archer should fit the above.
The airfields around London, where Cabair operates are:- Elstree Denham Blackbushe Redhill Biggin Hill
The person to talk to, at Cabair's head office at Elstree, is Simon Cooper 020 8236 2400 (he can also advise you on buying a suitable A/c, if required)
