I am looking for a cold caller, appointment setter agency Looking specifically for agencies

I am looking for a cold calling and appointment-setting agency to help me source clients with genuine needs for my service. We run a virtual staffing company specialising in EAs. The agency should be able to identify and contact qualified leads using tools like Apollo or Clay, manage cold email sequences, make cold calls to prospects, and help set appointments directly on my calendar. I’m looking for a long-term partnership. Please include your past work portfolio when submitting your proposals. Only looking for applications from agenices.
