I've bled my brakes myself using the "push the pedal" method, just need to come up with a way to prevent the pedal from moving back up until you set the bleed screw.
You just need a small container with the hose down to the bottom, Then put some fresh fluid in it to ensure the end of the tube is always submerged. When you lift off the pedal, it sucks fluid back in, not air. Age old trick… 
The key in all of this is that air doesn’t seep around the bleeder threads when they are cracked loose. It’s not always an issue but when it happens can be a pesky thing to deal with. I know people who have used vaseline or other concoctions to provide a temporary seal while the bleeders are cracked loose.
