5000 hours is a long time, but you can do it in 5 years with under 3 hours per day. That's within most people's means though you would have to make sacrifices.
Actually about 4 hrs/day...when figuring out approx billable hours in a year a good estimate is 50 weeks @ 40 hrs/week, so 2000 hrs/year full time (8 hrs/day) or 1000 hrs/week half time (4 hrs/day)...
