Have you looked at any communities?
I can’t guide you to any specific guild, because I always join social guilds…
But in one of my horde guilds, we sometimes arrange some picnics to SW 
All in all, I think you just have to be pushy in you guilds to get some pvp/raids/ganking started.
Having a little scan through the community forum I see that there is a community for the horde (H) PVP community <For the Horde> 
You should be able to find some people in here, who can help with both guides for gearing and other stuff
