Attorney Drunk Driving

How hard is it for a first tie DUI offender to get a restricted license?
I am being charged with a DUI which I regret and have learned from. I hope to retain some rights to drive to and from work. I live in California. Is there a need to acquire attorney services to ensure I get this? I would like to just pay the fine, do my classes, serve the penalties and get on with life (and never drink and drive again.)
you can get a restrictede license, but it is much easier to do with the assistance from a lawyer.
