Hey there! I am a part of a newly formed guild that I feel like would be perfect for you.
We are casual right now and only running normal raid as we help people gear, learn the fights, and just have real life stuff come up. Most of us have kids and jobs that limit us to being super hardcore.
We raid right now on Tuesday and Wednesday from 9 Pm to 11 Pm, I know you asked for weekends and not too late but hopefully that works. We also are on running keys alot during the week and weekends 
Hope to hear from you soon, here is a post we made and how to contact me if interested.
