@brettcarr, there is VMware's initiative for vROps plugins developers on VMware {code}. From its description:
"The VMware vRealize Operations Program enables our partners to develop vRealize Operations Management Packs using vRealize Operations APIs and SDK."
So I suppose you can get there much more help - I did not try myself but I suppose I will:-)
You can read more on Program page as well as you can register for access there as well.
There are similar programs for other products eg. LogInsight.
I am not sure but probably before registering for any of those you need to have your VMware {code} account if you have not get one yet.
