I am also considering using one as I now feel like I need my own fulltime staff..
before when I only had a few sites, all was fine, but now that I am closer to 100 sites, it has become alot of daily work & I am considering outsourcing some of that grunt work..
Over time, I have seen many compliments & kudos to
http://www.webmasterlabor.com .. you may have seen posts from Gene, aka $5 submissions..
from reading his posts, and his replies, you can tell alot about his personal character. His character traits from what I have seen on this board are that of an honest person, one that has high ethical standards, an excellent sense for business & loyalty to his clients.
No, i have never hired them or used them, (yet), but bet your ass that when I am ready, 100% sure they will be the ones to earn my business....
I'm sure others will post great things to say about them too,,,,
