Welcome! :cheers The contest is a great place to start in of itself, there are some amazing concepts there.
Another good place is Xander’s wonderfully useful videos on converting Battle for Skull Pass Dwarfs. These vids are amazing tutorials on creating crew.
If you like hat or helm (really old) style more just look around and you can get some ideas of how to do them. Remember, with this hobby everything looks harder then it really is, so don’t hold back! Make what you like! 
Hope to see you around. What God are going for with Chaos, or are you going multigod? For Chaos I always go Nurgle, except for my Chaos Dwarfs, who follow their own god.
