Help get iPhone Push Notifications Working

We have an already approved and active iphone app... but the PUSH notifications are not working. We think we have setup the payload and everything properly, but the phone is not receiving the notifications and we are not getting any errors. We are using PHP to generate the notifications. We need someone who can help with this ASAP and who understands from start to finish how to do iPhone PUSH notifications. Must: - have decent english - be available on Yahoo IM - be available during some US business hours - have portfolio of app(s) that are live and use push This job will likely just be a few hours long (might be as simple as correctly installing a cert??), but you will get a perfect review from us and a great piece for your resume (the [[login to view URL]][1] iPhone app!).
