Also worth noting that just about any/all casual guilds will accept players of any class.  Only a few guilds on Green have strict Class recruitment guidelines. 
 
Even then if you get yourself level 55+, show a willingness to consistently attend raids and are not an absolute prick you can certainly find yourself a raid spot in even the topend guilds as a Druid. 
 
It's a very long road to 60 -- play the class you most wanna play.
