social media marketing and management

I'm setting up a new website up for an e-commerce brand I'm launching. I'm currently looking for: An individual or team that can produce/create 1 social media post per day and can adapt for + distribute across 5 social media platforms (Instagram, Facebook, Twitter, LinkedIn, TikTok). Please give, an estimated cost based on that and let me know if you need any more information to provide a quote, I'm speaking to a range of vendors and once I know the expected budget, we'll be able to take the conversation forward.
