I think as soon as possible.

As soon as possible более распространено, чем as quickly as possible, но оба варианта верны

спасибо большое!

Есть ещё аббревиатура ASAP: We need the report completed ASAP.

These are used in different ways: (1) I’ll get the report to you as soon as possible (=it’s not in my control - I have to wait for it to be finished and printed; or it’s in my control, but I’m stuck in meetings all day, so I’ll do it at my next convenience.) (2) I’ll get the report to you as fast/quick as possible (=instead of mailing it, I’ll send a bicycle courier so you get it within then the 15 minutes)

Thank you so much.

my pleasure)))
