Post Gearbox issues

I am trying to develop something and it requires a REALLY REALLY small gearbox. The motor I'm using can get up to over 7000 rpm and it has a Dynamic Friction Torque of 1.35*10^-5mNm. The are going to be a total of 4 motors in my development. This adds up to 5.4*10^-5mNm. I need it to move a weight of ~12Kg. Can anyone help me figure out what kind of gear ratio I need to get this to work?
