John AsiPlanet,
There is a guy here at the Ballarat Airport who does Joy Flights in a StrikeMaster Fighter Jet! He will get you up high enough for an Earth shot.
You should get quite a remarkable curvature shot up very high!
Here is the link. It has prices etc.

P.S. Go for the Pluto shot! It's 2003UB
313 (the 10th Planet) that will be hard to get!
