Thanks guy´s for the replies! I kinda have the feel that maybe a AS-350BII would be cheaper to operate for sling work than the UH-1H now! I don´t have enough work for a B-407 yet.
To "Hilico" I must say that in my experience NEVER ever trust anything that the manufacturer of a helicopter tell´s you!!! Although "if" I would trust any one´s word it would be the word of Bell helicopters.
Mostly the people in the field who operate these ships day to day are the one´s to ask and the one´s who know the actual cost of running the helicopter types.
I am a "BELL" man, but thats mainly because I know them and I know what I have, they break down and have their problems like any other helicopter. But I´ll try everything to get a Bell aircraft to do the job before I try anything else.
