Contract proofs in Los Angeles?

A client is looking for a proofing service in the Los Angeles area that can make contract level proofs from his images so he can check color before sending on to his clients. Does anyone have a recommendation for a place in LA that does a good job with these? (Preferably in the Westside/ South Bay area.) Thanks!
