SQL Question - Visio

I need help creating a visio document containing the tables for the company and the information listed below.

Please make sure it is 1NF, 2NF, and 3NF (do not worry about 4NF and 5NF).

Here's the information on the company:

A Job is a single service call to a customer to fix some sort of plumbing issue. Over the years, a customer can use Fixinyerleaks many times. For each job, the plumber will record their hours and also record all of the materials used for the job.
