I am an aspiring web something or other not really sure what actual title would be. I mainly do (X)HTML/CSS work, but also know photoshop and some scripting/other (PHP mainly, Javascript, XML, and SQL). Also I already had a job coding websites in HTML/CSS for the University of Massachusetts. However im looking for places to build up a portfolio I can use to get even better jobs. Ive looked on http://programmermeetdesigner.com and monster, but half the time the people dont know what they want. They post ads like web designer needed required skills: Photoshop, Illustrator, HTML/CSS, Ruby on Rails, PHP, and AJAX. I dont know how they get to thinking RoR and Ajax is web design. However I usually dont get chosen because I dont have any sortof portfolio to show. So I was wondering if there was anywhere that has like contract jobs, another difficulty is that im still in school so its hard to like goto an office for a job, and other what not. Thanks for any help you can give me.
