Those symptoms are commonly an airflow problem, such as a dirty condenser or a fan clutch that isn't working. Basically once you're at speed, the ram air is providing the airflow.
Question, can you rev it to 1800-2000 rpms while stopped and make it get cold, or do you have to be moving..?
Have you check the high and low side pressure? The symptoms you describe are close to what happens when an empty system is recharged without pulling a proper vacuum.
I do a/c all the time, sounds to me like your condenser is dirty, wash it out well. It is a a fact that your a/c will not work as good at idle as it will when you are moving. Physics, and boils law come into play here.
