Need Some Advice on How to become a freelance Contractor

Hello Everybody,

Right now I have a decent full-time (37.5 hours a week) Web Development job. But I am looking to do some stuff on the side. Looking at all the work involved in starting one’s own web-development business, I am thinking of just doing contract work via websites like Elance | Outsource to freelance professionals, experts, and consultants - Get work done on Elance and [URL=“https://www.odesk.com”]https://www.odesk.com. I haven’t really done much contract work before so I am trying to polish up my resume, linkedIn profile and the likes to make myself marketable. The main problem I have right now is that most of the Web Apps I work on at my job are Intranet applications and I do not really have a portfolio of work I can present to prospective clients. Can anybody give me neat ideas on web apps that one can build that would look good in one’s portfolio (I can build the apps, I just need good ideas of what one can build that will look good in one’s portfolio as a contractor).

I am a PHP developer (Zend Certified Engineer - PHP 5) , proficient in javascript (JQuery is my best js framework), css, able to adhere to the xhtml 1 strict standard and also knowledgeable about accessibility and SEO techniques in web-development.
