If you know html/css/js/php and stuff you can stand a pretty good chance at finding a career doing web design, but by no means is every site you're going to do going to be flash. If you can handle doing html, css, js, etc. now and then in combination with regular flash work, you will have a very marketable skillset. If you can get some print knowledge you should stand a very good chance at getting a job. However nothing is ever guaranteed in the current industry environment :\
