Upload to Google Cloud via PHP

I need you to write a script that uploads a file to my google cloud account: [login to view URL] The script should ideally use some form of the Google PHP API client. [login to view URL] Or other another secure method if you have any ideas. I'm willing to pay around $30 - before I can award the project to you, you must read into this area and show me you have it working for your google cloud account. Thanks
