Need certification letter related to Enphase Solar and Battery System Software Settings

I am looking for a US based freelancer to help me obtain a certification letter related to my Enphase solar and battery system software settings. I believe the specific type of certification letter I require is a Certification of Compliance, and needs to include specific details regarding the software settings. Those details will need to be provided by me before my grid based electric provider grants me Permission to Operate. I can provide some reference to Enphase documentation and remote access to my system. The deadline for this letter is within a month. I look forward to your bids. Thank you.
