Sign in members via Google Auth PHP

I need someone to develop a really simple site that allows users to sign in via google. After signing in they are sent to their profile page where they can log out. Also, I need to store the user's First and Last name, and email in a mysql database. After every login I do not want to create a new instance of the user in my database, I just need the database to update the last login part of it. The first time a user signs in via google I want the site to create a folder named with the users email (without the @[login to view URL] extension) inside the "Users" folder that needs to be in the root of the project. There is no need to make a website design as I just need the functionality of this. Also, I need you to use your own google client id for development and then just leave it blank and tell me where to fill out that info at the end of the project. All this must be made in HTML and PHP. I think I have provided enough detail for a price estimate in your bid, so please bid according to the price you will charge for this, thank you.
