Urgently Want Unix Shell Scripting Trainer

I am looking to improve my skills in Unix Shell Scripting Training and looking to hire a Trainer who has in-depth knowledge in the area. I am fine with travelling to a nearby location for the class. The trainer should have hands-on coding experience and should be updated on the latest practice in Unix Shell Scripting Training. Unix Shell Scripting Trainer should be availble during weekdays and weekends.
