You could try the oQueue addon.
www.solidice.com/oqueue

It was designed to network players who want to pvp.
Blizzard doesn't necessarily want people to use it for non-rated BGs, but you can queue with a raid for rated bgs.

You can join any BGs that you qualify for; the leader chooses what the requirements are for their bg.
If you're looking for rated ones, then only go for those.
You can alternatively start a group/raid, set whatever minimum resilience you want etc.

When you start with the addon, press the Find Mesh frequently until it doesn't let you push it any longer.
That is submitting your Real ID to the 'Mesh' of others who PvP with oQueue.
