Prompt for a live signature in a fillable Form

I have a form that requires 2 signatures to be signed at the end of services rendered for that session. After a session, the provider and client both needs to sign the document to show/prove the session actually happened. How can I get Adobe to prompt for a live signature for the time the client needs to sign. I know I can use the digital signature for the Provider, but is there a way to get a timestamped signature for the client's signature without having to make a new digital signature?

I am using Acrobat to make the form using Form editor and adding fields to the document. I was hoping the providers would use Reader when out with the client. I have attached a screenshot of the word document below. I have started adding fields to be filled out in Acrobat, just figured this was an easier way to see the form without the field boxes in the way.

Any help would be much appreciated.
