Hi
I have a 1yr old and now a 1 week old as well. I do probably 98% of my work online and any phone calls I do make I do them when my 1yr old naps. All of my marketing is with online classifieds, social sites, message boards, etc... So it doesn't matter if it's quiet or not while I'm doing that. I also do "some" local advertising, I have my hubby take fliers out on his way home from work sometimes
The income is amazing and I LOVE the flexibility of being able to work around my girls and I can take time off when I need it. Like right now I'm not working nearly as much since I just had my daughter BUT I still have my monthly residual check coming in from the work I did before
So back to your question more LOL you don't have to do a lot of phone work if you choose to do most of your work online and I have never done any person to person work.
