Welcome back!
I’m glad you’re not tied to a realm, because that Worgen is doomed, I’m afraid. 
Stormscale is something like 98% Horde, with almost no Alliance; Alliance wither on the vine there, so you will want to make any Alliance characters on a realm that can support them.
I’m sorry to say it would be unusual for this ad to attract a guild notice. That’s just not how society in the game works.
There is a cross-realm Alliance Community Scared of Dungeons that I would warmly recommend when you are at max level:
but the essential problem is that it’s not very practical for people at max level to play with levellers - and about 95% of all gameplay is at max level, and in the other 5% levellers are divided by expansion. Yes, there are ways around that now, with Party Sync, but it won’t work consistently unless youa re levelling with someone specific.
You might get an offer to be Recruited, if you’re eligible. Recruit a Friend gives benefits for the recruiter. And sometimes it does work out. But too often the recruit is abandoned, worse off than they were.
I hope you do find some group to join.
