Machinima is a rapidly evolving and maturing genre and could be a point of springboard for your ambitions. Possibly setting up a collaboration between folk with the technical ability and imaginitive scriptwriters could be productive. The technical side is choosing what engine and when to go with the technology(not only that - original ideas won't have licensing or copyright problems)....just a suggestion
PS. you must visit Stirling Castle - the BBC made Colditz there in the 70s....very impressive place.
