How do I sign up for non-trial version?

Hi,

I'm struggling to figure out how to sign up fpr Adobe PDF services. 

A couple of weeks ago I signed u for the trial, received credentials and sample projects and started using the service. Now I need a paid account so we could continue using these services.

My company's sys admin was directed to sign up through AWS and we found the service subscription there but how can I get the credentials from that subscription?
