I spend all of my working hours defending people accused of crimes. However, because I chose to be a public defender, you can't hire me, I have to be appointed. If you are charged with a crime and don't qualify for a public defender, you should probably talk to a reputable criminal defense lawyer.
Brian Tannebaum, a criminal defense lawyer in Florida, wrote an excellent e-book, "The Truth About Hiring a Criminal Defense Lawyer" that covers the process of finding and hiring a criminal defense attorney. Read it before you hire a lawyer for your criminal case. It'll answer most of your questions and make it a lot less scary.
