Hello! My guild Evolved might be a good fit for you! We are an 18+ community and most of our members have families, jobs, etc so we understand the importance of real life coming first. Because of this, we do not require 100% raid attendance. We run multiple raid groups, so plenty of room for you! Everyone is super friendly, mature, and a ton of fun to be around. 
We like to focus on having a strong community as it makes the game so much more enjoyable! We do all kinds of things besides raiding such as M+, arena, world pvp, dungeons, etc. We just like having fun together! 
We raid Tues/Fri/Sat from 9-11 pm EST with an optional hour on Fri/Saturday. Evolved is an Alliance guild on the Proudmoore server.
Everyone is super friendly and helpful and you would have no problem getting questions answered, advice, etc as you further journey into your WoW adventures!
