Having owned 5 r44 and 3 as350 and been in your position, I would suggest finding a nice 1990's era B or BA, for private work you don't need more power of the B2/3, but a huge increase on the ec120 which has scared me a number of times even with four people and full tanks. You should be able to find one, give it, new paint and interior to your standard and not pay more for it than a ec120.
