You will also need a CPL to be a jump pilot in the USA. You are also pretty unlikely to get a job in the UK these days as a PPL. Parachute dropping is a very intensive activity and requires skill and precision as a pilot. Most clubs I know will not look at a pilot with less than 500 hours or without a CPL and IR or IMC. Then you get into the individual type requirements, tailwheel, turbine etc.
