Telemarketing/Cold-calling

I am looking for a freelancer with experience in telemarketing and cold-calling. My target audience are businesses, so the freelancer should be comfortable calling these contacts. My main objective of the call is to generate leads, so the freelancer should be able to take a lead through an initial sales process and come to a clear outcome. I do have a script prepared which the freelancer should use. The freelancer should demonstrate excellent communication and sales skills, have sound knowledge of the product/services being offered, and be capable of dealing with objections. Success in this role will depend on the freelancer's ability to engage in conversation, build rapport with leads, and move them closer to conversion.
