Moving a gearbox and tailshaft interstate?

[lilmattie]

I tried to do a search for similar questions, but the few that I found weren't that helpful.

I live west of Brisbane near Ipswich and I'm looking at buying a gearbox and drive shaft from west Melbourne. All up it weighs 50kg or less (can't get an exact weight from the seller). The seller assures me he can pack it ready to go.

I don't usually buy larger parts interstate. Can anyone recommend a good door to door courier or transport service?
