Create unique list based on date

Hello!
Sorry if there is topic like this, but i just didnt find any simple solution of my problem here.

I have order list that i need to extract all unique names based on the date of the order.

column A - date, fill with order dates
column B - client, fill with rapeating client names
E1 - citeria date
G - the start of the result unique list
I am using excel 2010

How do i extract all Unique clients (column B) that made order after criteria date(E1)? The results lets say be plased from E2 and draged down depening of the number of results.
