Hi there!
Let me extend an invitation from OOPS Inc!
I could write out some big story about who we are, but if you just click the guild name right there, it’ll take you to the Guild Recruitment page our Editor-in-Chief of AI Generated Content has worked very hard on, with all the information you’re probably after. 
Our Discord is very active and we’ve been doing some group content together. But we’re saving our Raid efforts for Midnight.
If you’re looking for something a little bigger and more established, From Scratch might be more to your liking. They are currently clearing Mana Forge: Omega on Mythic difficulty.
If your seriousness means you want a bump in progress, you could try Temporary Solution
I like OOPS Inc better, but I am very much biased.
