Browsing around I found that a lot of people making one very big mistake.
They associate freelancing with making money in internet, data entry, affiliating, and banner clicking.
The real freelance is the one that has very good background and knowledge and ready to meet clients and add value to their organizations. To be an external eye that can see some problems and deliver solutions.
Maybe sounds a bit old-fashioned but the business really needs that type of independent people who experienced different best practices.
