Setup social network posting API

I need someone that has had experience in the social media setup process for https://stackposts.com/. I have all installed and tested now i need to create the admin settings and now link with Facebook, Google My Business, Instagram, ​Linkedin, Twitter and Youtube via admin. This is a small job and should take 2-3 hrs in total. Please read the information on stackposts.com and make sure you understand the setup process for social linking (NOT INSTALLING SCRIPT, THAT IS DONE). please quote a price to do the job not a price to start a discussion. Thanks.
