Just try and find contacts and when you find them, keep them! keep in contact with your old work place every month or so, and keep sending in updated reels to the studios. Somthing will happen eventually, just dont stop creating, go to all the festivals you can, anything where you can meet people.
Be visable, and keep emailing. Good contact is the key, join networking sites like linked-in, they are good too. Through that i know people at pixar, ILM and most the major soho studios.
