its all automated, and the returned NXT must go back to the lessor account, Im not set up to sent it anywhere else.
I honestly cannot tell you how much you'd get though, with any amount.
I will have leasing on Ardor as well. Currently I have leasing set up on the Ardor testnet chain. http://theardorpool.dynu.net.
I run this pool for free. hopefully to get as much NXT power forging as possible.
If possible, please send me a PM when your ARDOR pool goes live. I will lease my ARDOR balance right away and currently have my NXT leased to you as well. Thanks!

His Ardor pool is already up and running.
