So I am thinking I need a change

I have been doing this civil thing for about four years now. Sometimes its been fun. Sometimes it has been dreadfully dull (especially when I worked for the darkside). However, I miss doing criminal work, which was what I went through law school intending to do.

However, after four years, I realize I am not qualified to do much more than make certain appearances in court on criminal matters. Now how do I go about getting back into doing criminal work again? Was much easier when I was still in law school and had the contacts.
