Hi! I myself am now providing paid support for Let's Encrypt integrations.
I was one of the developers of Certbot and am a co-author of the Let's Encrypt academic paper. I've also been one of the most active members of this forum community since the beginning, and have successfully helped thousands of people here solve their problems.
I continue to enjoy helping people free of charge on this forum (in public). If you'd like help from me privately, including via an audio or video call, or remotely debugging your certificate problems, or figuring out an integration issue, please get in touch with me via my web site above.
