an appointment setter or a sales development rep
The people who are really good and skilled in appointment setting , sales developement , nowadays will do their own thing ( freelancing , referral or affiliate marketing , etc ). So , in my experience if you get to hire any appointment setting , sales developement people , you will get all the " dried left overs " with ineffective skills and you will waste your time and money on them.
Nowadays , internet marketing offers such wide options to make money , that even uneducated housewives with some good skills say in cooking , stitching , etc are making good money from their homes (Youtube ,etc).
And if you are nowadays looking for appointment setting , sales developement people , then you are outdated. Nowdays , businesses do their outreach , marketing in the digital media , integrating automated tools for appointment setting and yes , even brick and mortar shops like barbers , salons are now more and more doing it this way.
