Another option would be to shotcrete it with benonite. I don't know what the cost is, and you can get leaks. I have not seen a liner that size with any underlayment. Any leaks you get are going to be minor in the overall size of the project.

I would have about 20 guys, a way to hold down the liner until you get it all out and ready to fill. If the wind gets under you are royally screwed. It will start knocking it around like a kite. You need to be ready to fill ASAP, because if you have any ground water coming in underneath, it will lift that liner like a balloon.

Also, I am sure your looking at at least 10K for the liner or more ..
