Piste to Powder looks like it’s €380 for a private guide, and €135 per person for a random group. So if you get 3 people you’re ahead.
There’s only 3 levels. You’d go 1 or 2 and your daughter 2 or more likely 3. It’s hard to tell without consultation how 2 and 3 would shake out. It also depends on goals.
I would ask if level 3 is likely to include rappelling into couloirs.
There’s also “Open Touring” groups. I take it you personally don’t want to skin up?
>You need to be Level 2 or 3 skier with good fitness level, comfortable skinning 400 – 1000m vertical, 1 -2 hours. Safety equipment provided. Please bring touring skis, skins, backpack and helmet or rent online at Jennewein. Don’t forget energy bars and water!<
It looks like you’d need “3 weeks” of off piste guided experience to make level two. But that doesn’t really translate to North American skiing, where much of it could essentially be “off piste”. I suspect you’d be fine with level 2.
