Career help!!!!

I am currently 21 years old and have four solid years of computer experience. I work for a computer consulting company making $15.00/hour doing system administrator work at three different locations. I currently have 24 college credits and have an MCP certificate. I am pondering on the thought of just going back to school full time for an E-business degree or looking for a better paying job. Any thoughts or comments would help me out big time.

Thank You
