I've had 100% success with the one-man non-vacuum bleeding. Two-man bleeding has been problematic

can be done by one person (no assistant needed)
1. Put about 1" new fluid in a clear glass. Place glass on ground. The fluid prevents air from going back up into the cylinder
2. put a hose from the bleeder to the bottom of the glass, making sure the new fluid covers end of hose
3. Crack the bleeder slightly
4. pump the pedal while you watch the glass (lie on the ground with the door open, and work the pedal with your hand). When air bubbles stop coming out, it's done. Often this only takes two or three pumps.
5. tighten bleeder
6. top-up the master cylinder. DO NOT REUSE BRAKE FLUID

Any spilled brake fluid should be rinsed off painted surfaces with lots of water.

By the way, a common problem with clutch not working is the clutch master cylinder leaking internally. So no fluid leaks out, yet it won't fully activate the slave. To test if that's the problem, take the cap off the master, and watch while you pump the clutch pedal. If the fluid level RISES as the pedal goes down, the first piston seal is leaking. In extreme cases a jet of fluid will shoot up
