Hello! =D
Ministry of Silly Wipes could be perfect for you then!
We raid Saturday and Sunday from 20:00 Server time, and do Mythic+ frequently throughout the week, with players running at various levels.
Have a look at the thread I linked, and if we sound like what you’re after, please add me for a chat!

Bnet: Westie#2496
Edit: sorry, its early and I just realised you’re asking for a Horde guild on Draenor.
If you’re struggling to find something there you’re welcome to give us a try anyway =)
