Horde - Ret pally looking for guild to raid uldu/toc

Hey guys, i'm a ret pally 4.8k gs. I find it impossible to progress due to low gs for global chat raids and guild applications.
Already farmed everything with eots, farmed icc ring and i'm close to my first t10 piece. Also bought 10k on a couple items. But still isnt enough.
So yeah, i was looking for a guild or some ppl that are willing and cappable of organizing runs.
I have raided from uldu to icc last season with a guild as udk, so i know fights from that perspective. But i dont know ret pally specifics on each boss.
Anyway, thanks in advance. Worst case scenario i wait till april and start fresh.

(If you have any information about guilds raiding uldu/toc, please also let me know. Can speak spanish/english)
