Can Some 1 Fix my dialplan

I have a toll Free provider. and a calling card by AT&T.
now here is what i want
when i dial 3323.
It should dial the 1800 no of AT&T, wait for 2 sec, punch in the , wait for 2 sec, enter 14 digit sec code.

This would make the call process simpler so the users will just dial 3323.

Plz Help
