Microsoft SQL Server 2014 Management Studio Security Help

I wrote a database a couple of weeks ago for an assignment, the assignment for this week is to take that Microsoft SQL Database, which I wrote in Microsoft SQL Server 2014 Managment Studio. 

I am supposed to password protect the database, I have tried a couple of different things I found online but nothing has worked, so I need help trying to figure out how to do this apparently.

I also have to create a matrix to indicate the permissions (read, insert, delete, modify) I would grant to different users of my database.

I have to create at least 2 different users, and implement their permissions unsing SQL statements. 

I also need assistance with a major project in doing the Index and the screen views (forms in access).

I am willing to pay up to $30 depending on the level of help that you are willing to give me on it.

The big issue is the person that I have a deadline of tomorrow by noon or earlier, the earlier the better.
