Is it possible to bleed disc brakes without the expensive kit?

I'm building up my old Hardrock with some upgraded parts. My Hardrock has disc brake tabs so I put disc brakes on it.

We recently got a donation of some disc brake parts including a complete front/rear set of Avid Juicy 7 brakes with rotors and a disc brake wheelset. They are all mounted on my bike now however the front one need to be bled badly, it doesn't even work.

I found out that the bleeding kit costs roughly 60 dollars and that is quite a bit of money that I don't have. I'm used to bleeding car brakes which is pretty simple. You pump the brakes a few times, hold the pedal to the floor, open the bleeder valve on the caliper, and repeat til air no longer spits out of the bleeder valve. Is bleeding a hydraulic bike brake system anything like that?
