Cold calling for smma service

I am looking for a professional to help me out with cold calling potential customers for my social media marketing services. The length of each call should be 10-15 minutes to ensure that all details can be effectively explained and any questions answered. My services include social media marketing techniques such as optimizing content, following specific strategies and increasing brand recognizability. I am hoping to find the right freelancer who can help me successfully market my service by reaching out directly to clients.
