To get the rear tire of my bike off the ground, I use a concrete block, a two X four, and a "scissors" car jack (the kind that comes with every car).
I put the concrete block on the right side of the bike, lay the 2x4 across the block so it extends under the bike, then I place the scissors jack under the 2x4 on the left side of the bike and jack it up (so the bike is slowly lifted off the kickstand and raised and leveled). Make sure the 2x4 isn't hitting anything but the frame, and i put the jack and the concrete block as close to the frame as possible.
If you can pick up a motorcycle jack for $50, the method I use doesn't sound all that great, but it works for me.
