Handle my social media pages, establish a digital presence for the purpose of selling real estate

Hello, I am a real estate agent in Canada. I’m looking to establish a social media presence with the intent of selling properties and real estate. Canada does have specific privacy laws, but I will be able to work with Freelancer to ensure compliance. Would like to have some sort of monitoring for leads and messages so they are always responded to immediately. Looking for the best possible solution and open to ideas
