Returning Player LF Raiding Guild

Returning wow player here looking to try and raid again. Would like to play lock but have rogue and holy priest as well. All at 265 or better with 4 set. Looking for something that clears heroic and pushes into mythic.

Times available to raid - weekdays 6-10 pm EST. Let me know what options i have.

Thanks for your time.
