I have just launched a new freelance auction website, Expert Freelance Jobs provides a market place where both freelancers and employers alike can come to find what they were looking for.
It is a freelance careers website for programmers, web developers, designers, writers, data entry & professionals.
It makes use of simple open source technologies freely available on the Internet such as Joomla which is the CMS engine behind the website.
