I don't think heatsync would have the machinery for that, if you're looking for some heavy duty machinery at a makerspace go to the techshop in chandler. As for using a gear to go to the ball screw, would it not be easier just to drill a hole and pin it? If you're looking to get a reduction from the motor to the screw you could always just use a couple regular gears; one on the motor shaft and one on a shaft that extends past the screw. But if you need a reduction you could just look at getting a different gearbox for the motor and pinning it.
