Live Call Answering Service

[Nova Mendoza]

Can anybody recommend a live answering service for absentee mailers that will be sent out? 

I want to make sure there is someone to answer incoming calls and do a quick screening before I call the mailers back. I'm a mom working from home so I need someone to catch the calls until I'm able to follow up. I'm just starting out so I won't be sending out thousands of mailers. What service do you recommend or any advice you can give is appreciated?
