Best signature tool for fully automated Prozess of Forms based customised contract and e-signature

Hi,

I am fairly new to Power Automate, but starting to love it. Did a bit of Research for the following, but am a little stuck.

I would like to build a fully automated signature process starting from a entry form in Forms, creating a customized word doc for signature with all the custom fields and a custom agreement name (I got that far), and now I would like to pass this on through Power Automate to an e-signature tool using the variables from Forms, preparing the doc for signature and sending it out to the person that filled out the form and then back to me after its signed.

Is that even possible?

I thought DocuSign, but that seems horrible complex to achieve the above. 

Anyone built something similar? Any recommendations for other connectors? E-Sign? Adobe Sign?

Thanks heaps!

Carsten
