For a job like this...I would try contacting a reputable company in your area. Then ask to see some of their jobs with the same type house and job you are going to do. These guys are the experts and if they want your business, and you keep them honest, you will learn more first hand than any other resource. Contact more than one company ...you will spend as much time trying to look things up, as you will with someone showing you the jobs.
Any company worth their salt will show you around, and help you learn.
Just my professional opinion.
