I need to review companies that can supply me with someone that can take calls from me during central time hours. I need an assistant to follow-up with potential customers and employers on my behalf.
Odesk - highly restrictive, and too hard to pick out the serious candidates, no oversight by anyone but me
Elance - less restrictive, but nobody in charge other than the person being hired, no oversight
Freelancer - almost non-restrictive but no oversight
I need a company that can find the right person if the first one doesn't work out. I am trying to leverage economies of scale and would prefer someone in the Philippines to other places. Time zone works out ok there.
