A+, Net+ , how to get a foot in the door now

I am looking to get out of my current occupation and become involved in Network Support or even a help desk job to get started. I would very much like to get into Network Security in the long term. However currently I have Net+ and A+ cert and thinking about going for msca or msce. I am having a hard time finding entry level work in the computer arena. If I could just get my foot in the door somewhere then i know that would help.
Currently I have a friend who is going to let me work on all there computer needs 4 hours a week. Does anyone have any recommendations on getting started in the a computer career?

Thanks for your feedback.
