Hey! We raid Tuesdays with a social/casual run where we typically do full clear of Normal for the first few weeks, and then after we are easily clearing Normal, we will start working on Heroic after the full normal clear, and we usually get AOTC after a few months in that group, and we have some of our main raiders in on alts (or mains sometimes!), socials, casuals, friends of the guild, etc that come to the Tuesday night runs. We start raid at 9pm eastern on Tuesdays and we go for a few hours, and it’s very casual so if people ever need to go at a hard stop time (like 11pm for you), you’re welcome to step out at that time. 
Anyone who wants to pursue a more hardcore raiding environment is welcome to go from the Tuesday run into the Sun/Mon runs (but it sounds like that might not be up your alley for now haha).
Please come check out our recruitment post for an idea of our guild and raid environment and see if this is a place you’d be interested in!
