Honestly, it's up to you, but you have to begin somewhere even if it means at a low pay small company that doesn't care about "its website & pay." The skills you will learn working in a team/work environment is invaluable. The goal is to first get your foot in the door which ever way you can. Establish yourself, build some reputation and credibility. This is real experience, the kind that will eventually get you to the job you desire.

Always remember, no matter how good you think you are, there are other people out there that are better than you. You've had 4.5 yrs of self taught experience? When I was your age I've already had over 10. It was never above me to take that $50k job or that sketchy Craigslist posting that netted me just $500 for weeks of work.
