social media integration

I'm looking to hire someone to help me integrate social media into my business. Specifically, I'm looking to have Facebook, Instagram, snapchat and tiktok integrated. I need both the posting and retrieving functions of each platform to be enabled. The ultimate purpose of this integration is to enhance sales and marketing. To that end, features such as content calendars and analytics will need to be included. I'm looking for an experienced professional who can use creative methods to get maximum results from this integration.
