Power = 950 * 9.8 *10/60 =1551w, so choose a motor with about 2.5 horses. The reduction ratio depends on your output speed. Yours is 1400 rpm, four-pole motor. If the speed you need is about 10 rpm, the reduction ratio you need is about 140 rpm. Contact me if you want to know the details. I hope I can help you.
