giving app certificate to developer

I've hired a developer to create the next version of an existing app. The code is done, but they can't submit my app as an update because they need the app certificate from the Mac that had the previous version on it (mine). I can't remember how to make this happen, or where to find the certificate to give them?

3G,


The workflow linked to below is what is recommended when the team agent isn't submitting the app:
