It usually does not take that long but, it states it can take up to 72 hours for a review to be moderated.

Yes, it is someone that see you that creates your profile, then, see my reply to the thread below.

the average for posting reviews is around 3 days.  If it's your first, and the reviewer does not have any, or some, reviews, it might take longer.  Admin likes to make sure the writer and the provider are both legit.  If the guy is a well established reviewer, and the provider is also well established, it may only take a matter of hours.

No, you cannot create your own profile.  That job falls to the first guy that reviews you.  You can change it after your profile has been created by contacting admin.

Suggest you read the self help center, it may answer some of your other questions.
