You're not going to get much reception with this method. You're better off just posting what you want in the forums. Whether it's private (I assume you mean that it'll just be for you) or not is irrelevant, and if you mean proprietary (which is moot), there are no secrets among addon developers and once your addon is made public everybody will be able to see the code anyway.
So someone who might be able to do this here's part of a message between me and Necrovaris:
Thanks for getting back to me.
The first addon we are looking to get made relates to the Yor'sahj the Unsleeping boss in 4.3.
Part of the encounter is that he spawns 3 (or 4 on hardmode) colored blobs, where you can only kill 1 blob and the other 3 give him more abilities.
What I need the addon to do, is when he spawns the blobs, for it to detect which blobs spawn, prioritise them, and then send a raid warning something like
"KILL YELLOW - GROUP UP AOE"
The blobs when spawning give a blizzard warning, so you should be able to use that to pull which colors spawn from that, there are quite a few combinations, so if you wanted to add in say 2 blob cominations, I would be happy to add the rest in myself once I see how the code works.
