Greenham would have been ideal in terms of the airfield itself and the nearby transport links, it's been discussed on here many times. Slighty more of an issue might be the Govt. "establishment" that lies exactly in the undershoot for the westerly runway about 5 miles from the threshold (have a look on google earth).
Such a pity that around 500m of Blackbushe's main east/west runway was cut up (at the eastern end) in the early 1960's, following it's demise from being London's 2nd airport. It's location is still ideal in many ways, and the land to put the runway back to around 1800m is still there (as neglected common land).
It's flat, well-drained, and has fairly unobstructed approaches. It is in a affluent, noise-conscious area, but surely better to start with a place that has at least some comprehension of aircraft noise (GA, including spamcans up to medium-size heli's and small/midsize jets) rather than somewhere like Wisley where the noise comes mainly from LHR inbounds holding at OCK.
