Anyone knows how long it takes to become a member from Newbie?or how to make it happen faster?any advice on that subject ?

Usually, when I need to convert my bitcoins into fiat, I do it through a real life meeting.
Why? because there are 0 fees, and because it is the most anonymous way of converting virtual currency into fiat.

The only risk while doing it is that you can't know who are you going to meet, and this person could just scam you, or treat you.
If you are looking for a zero fee transaction that could be your pick.
