I'm not sure, but I believe, on our roadmap there is development of a WHCMS plugin for our business on ssl certificates. If you ask someone to code a PMG WHMCS plugin for you, I then may be able to refer you to a developer based on our experience. For sure, a PMG WHMCS plugin is not available yet, so it would be required to be developed and no, we don't see currently the need for development, so we won't sponsor it.
