E-sign Development (PHP)

I am looking for a developer that is familiar with e-sign. We would like to use https://developers.esigngenie.com/ but are open to any e-sign platform that you are familiar with. I am looking for someone who can map about 10 pages of e-signature fields. We will provide a php document with all of the objects(data) and you will have to map the data to esign API and document templates (pdf) so that we can generate pdfs for esignature.

We are looking for someone with experience with e-sign development.
