You could consider RaidPlay for your raiding needs: [A-PvE] RaidPlay - Raiding Community back for Shadowlands
We raid once a week, and we’re a raid community, which means you don’t have to join a guild to raid with us. Instead, you can join any RP guild you want. Our goal is just to clear heroic every tier, though, so if you’re after mythic raiding, we aren’t going to be it.
