Returning Horde (Switching Alliance) Healer LF Guild

I will get it out of the way that the last time I seriously raided was back in Wrath of the Lich King. I have been playing the game since then but didn’t have a consistent work schedule so I didn’t raid (schedule is now wide open). That being said, I am considering a switch from Horde to Alliance, and am searching for a guild in advance. I am able to efficiently play any healer that is required, and am looking for a guild that raids preferably later at night (10pm or later start since I run an amateur HotS team).

Currently my characters are mostly Horde, so the switch would require me to level and/or boost a character and get them going. This is why I want to find a guild in advance, to prepare accordingly. Thanks!
