Want to create an email signature template in Sharepoint Online

I want to have a sharepoint page? form? where people can enter the following information:

Firstname Lastname. Credentials
Official Job Title
Department Name
telephone #, cellphone #, fax#

With the above information (If filled out) I want to display a template email signature (With the additional wording that goes on everyone's signature) so they can copy it into outlook as a signature.

What is the best way to accomplish this?
