I need Appointment Leads for a Payment Processing company

I am looking to hire a freelancer to help me generate appointment leads for our existing payment processing company. We are expecting 20 leads or more per week, and prefer for the leads to be contacted via phone. The project is for business use and the fast-paced nature of the project requires someone with experience in lead generation. We are looking for someone who keeps our best interests in mind and has a customer-focused attitude. It is also essential to have good communication skills and be organized and efficient.
