I need a person for the promotion of my business

I am looking for someone to help me promote my business on an international scale. Specifically, I need assistance with social media marketing. My target audience is customers around the world, and I need the promotion to run for 3 months. This person needs to be creative, have experience using social media platforms to develop campaigns, and be capable of understanding cultural dynamics on a global level. A track record in digital and social media marketing is key, and I would also appreciate any specialised knowledge, such as SEO or web analytics. Ultimately, I’m looking for someone who can help me promote my business in an efficient and effective manner.
