someone to help me with my social media advertising

Hi, I'm looking for someone to help me with my social media advertising. My primary platform will be Facebook, with the goal of increasing engagement. I'm not sure yet how long the campaign should run, so I'm open to suggestions and advice on that. Ideally, I'm looking for someone who is experienced in this field and who can help me develop a plan which will maximize my desired outcome of increased engagement. I'm looking forward to hearing from you and thank you for your time.
