Hiring virtual employees is not an easy task.
I can say this because i have an experience of this field.
Actually i wanted to hire employees for my site.I was looking for entire team of SEO and web designers.I had posted my project on e lance. BUT BUT BUT
I felt that there were many "Dummy projects".And those project were placed only to analyze there cost of the project. And we unable to understand that why our bit not get awarded.
So, the bottom line is wastage of time as well as money.
Than, one of mine friend told me something about marketraise company (www.marketraies.com) hire now concept.I read there proposal of virtual employees and get fully satisfied with there package.
And finally i am satisfied with there virtual performance.It's always better to give more preference to your precious time and money.
"SO,  SELECT  YOUR   VIRTUAL  EMPLOYEE  CAREFULLY , OTHERWISE IT WILL BE BIGGEST  LOSS  FOR  YOUR  FIRM"
