Are you sure that's a good plan. I sometimes take a friend on four but there are cons as well as pros.
I only get her to answer while I am busy.
The pros are I can end up busier and I don't have to text back missed callers. Sometimes the company is nice to have.
The cons are I can end up losing customers who don't like speaking to a 3rd party, I have to pay her money per client, I sometimes end up seeing skanky guys that no way I would let in, and on occasion I don't want her around. Company nice sometimes but other times a pain in the arse.
