Only do it if you love it!
I have vast experience with data entry, knowledge with excel, internet search, data mining, search sites, MS Suite, Google documents. Also I always respect the deadlines and I am focus and objective. Working with clients like Citibank, Itaú (Brazil), X-Box, Revelon, Nike and others.
Usually I brief the client very deep to be well-prepared to the first part of the project, for communication I like email or Skype and payments we can negociate, but usually I work with 50% in the start of the prject and 50% in the end.
