Following a third DUI in five years you will be declared to be a habitual violator.  Your license will be suspended for five years.  It will be a felony for you to drive during that period unless you obtain a probationary license which can only be obtained after two years of no offenses.

These sentencing ranges do not include the amounts that you will have to pay to have your license restored administratively which includes Drug and Alcohol Risk Reduction Courses, drug and alcohol counseling, and reinstatement fees.  It certainly doesn't include the amounts that your insurance will go up if you plead or are convicted.
