Cold Marketing Specialist

Looking for someone experienced in cold outreach for business services. Email, LinkedIn, etc..

Please do not respond if you are looking for a high salary up front. I have tried someone before who was recommended to me and found out was spending very little time on my project. I prefer at least part time committed hours, or even up to full time if you produce results as I have other services to add.
This would be to drive potential customers to either book a call or request a demo.
I am willing to pay a smaller hourly rate and bonus you on calls booked/ sales made.
