Milner is a billionaire. He could easily pay for a full-size satellite lofted up by one of Musk's $5M reusable Falcon 9 boosters in a couple of years... Double that number to build the satellite if you have to and he could still find the change in his pockets...
EDIT: and once I convince Milner to finance this boondoggle can I sign you up to be my lead satellite engineer?
