Quick help with web development (Github)

I am looking for a web developer to help me finish a project using Github. This is my first time using the platform, so I'm hoping to find someone who's experienced with it to help. My website is finished but to finalize I need help to add password protection to the website. Also, I need help in the shortest amount of time possible, preferably immediately. If you have expertise utilizing Github, and can work quickly and efficiently, please reach out to me as soon as you can with any questions or quotes. Thanks!
