I am helping a friend look for Cold Caller/Appointment Setter to reach out to prospective business

I am helping a friend look for the right VAs for his business: Cold Caller/Appointment Setter- the task is to reach out to prospective business options that are a right fit to use the app and then book appointments for us to go in and convert them. General VA- the task is to do the posting on social media and handling minor operations like appts, etc. Initially, roles are part-time. The rate is negotiable depending on the skills and experience with a bonus.
