Working in IT I've noticed that each day there are new help sites, tutorials etc to help you accomplish your task when building a web site and/or application.
However it still takes a lot of time to really know a concept or utility that you may need just once for your website. Sometimes a business just needs an expert in a niche field, to get the job done quickly and effectively.
This is where Gofix comes in - it puts people in contact with the relevant experts and provides those experts with a marketplace to find clients.
It has a lot of competition in a similar field (eg Odesk and Freelancer) but I have a hunch that Gofix.co can build its own niche.
