Approval Stamp

We receive many PDF invoices from suppliers.  I would like to provide our A/P folks of quickly adding a blank page to the document with an approval stamp with the following fields:  account no, approval signature, received date, processed data, and description.  I would then like users to be able to request signatures from other users through Acrobat DC.

I apologize if this has been asked before.  I wish I could contact Adobe sales and support for this information, but they don't have an email address listed.  I would happily pay for support if I knew who to contact.  There are no email addresses listed anywhere.  I'm not sure I want to spend the day waiting on the phone.
