Do it online....
I have a brother-in-law who works roughly 60+ hours a week and is in his dissertation phase of his PhD.....all online....all from a reputable and accepted school.
One thing about doing the classes on line - they are usually more convenient if you're working around a job. The bad thing is that you need to be self motivated. If you don't have the self discipline to sit in front of the computer for six hours a day on the weekends you aren't going to succeed at getting a degree on-line.
