as much as you want
Если тебе удобно на диване, то можешь оставаться здесь сколько захочешь.
If you're comfortable on the couch, you can stay here as long as you like.
— Суспирия (1977)
Я прикажу купить тебе таких сколько захочешь.
I'll order as many of those for you as you want.
— Подними красный фонарь (1991)
I'll give you as much as you want.
