You'll find the guild recruitment area at the bottom, just select your platform and region, although it's better to ask in the zone chat.
You can also go into the guild finder and find them. It would probably be more productive!
In game click G and on the left side of the window that opens select guild finder from the pull down and make sure you are searching for PvP and in the advanced options you can select your faction to make it eaiser.
