We did it!
I finally received the "MACHINE" (a little bit expensive ouch
!!! 230€ - 300$ US!!!)
and we (customers and I) decided to built the biggest we can! (11ft) the snow was good for the first experience! we managed to enter 13 persons sat inside!
I should trained a bit more to build quicker! we needed 5 hours to finish it!
Temperature at night inside was close to 4°C, and -3 outside (little bit windy)
One person wasn't able to get in! (afraid of!) so slept under tent close to igloo.
Now the sun made then almost disappear..
But it was a cool experience, and next year we should build them at altitude 1900m in a very windy area!

See you next year !! bye!
