Business entity regulations

I need to complete an essay and cover the following information. I have researched for a few days now but can't seem to find the information. Do you have any suggestions on the websites that would have this information.

1. Business Entity Regulations Paper
Prepare a description of business entity regulations in your state as they pertain to your current employer (I work for town hall which is a municipality). Be sure to include the following your paper:
a. Identify the business formation code(s) in your state. (Arizona)
b. Identify the address of your state's corporation commission.
c. Describe the process for obtaining an "annual filing report" for a corporation currently registered in your state.
