WTB several raid achievements

Hello everyone, I'd like to buy the following achievements:

1. The Undying

2. Champion of Ulduar (10m): still need Mimiron and Yogg
2a. In case of we clear a rather new Ulduar10 instance, I'd like to do the Algalon key quest chain by the way, what I need are:
2a-1. Iron Council hard mode to get the Disc, prefer I Choose You, Runemaster Molgeim
2a-2. Hodir hard mode
2a-3. Thorim hard mode
2a-4. Freya hard mode
2a-5. Firefighter conflicts with my main goal above, but in case that I fail and die in Mimiron fight, we can do this too
2b. I'd like to buy any other extra achievements that I dont have, along the way to Yogg

3. He Feeds On Your Tears (10 player)

4. A Tribute to Insanity (10 player) & the mount

about myself
my armory link: http://us.wowarmory.com/character-sheet.xml?r=Proudmoore&n=Nicorobin
I'm experienced in the dungeons above; I have the Rusted Proto-drake; I have done Insanity on my druid in 3.2.
I'm confident that I can avoid death in Naxx & Mimiron normal mode.
I believe I can avoid death in Yogg & Algalon fight, with a bit less confidence.
I believe I wont ruin an Insanity run.
