It takes rich dreamers to create a new industry. In-orbit infrastructure will have to be built, though probably not anything as exotic as a space elevator. One approach to get material down: create basketball-sized meteors during the mining process or in-orbit with smelters. Coat or cover them in a material that will make their re-entry less wasteful. Using some kind of thruster, direct these into a de-orbit ending on a raft thing in the Pacific Ocean or parachuted to a deserted area. For the more precious or dangerous material mined: use cheap glider-style re-entry vehicles.
