Unfortunately, Proof is not set up for firm use at this time and is only able to contract with individual process servers.
We have had an increasing demand for this type of “affiliate” model, and have plans to implement this feature in the future! We will be happy to announce when that feature is released.
In the meantime, we would still love to have you and your team try out serving with Proof! To get started, please have each individual create their own account here: https://www.proofserve.com/become-a-process-server
We look forward to hearing from you soon!
