Exercise Routine help

Hi I'm a single mother of a 2 year old girl. I am strapped for time during the day so I have no time for any gym's or runs outdoors. Due to no babysitters. So anyways, I am trying to lose around 70lbs in 1 year possible, yes! Getting there I am unsure. So I have only about 2 hours after my daughter goes to sleep to work out at home. So body weight exercises no gym equipment. Is there a routine exercise I can do to burn a lot of calories? I am always under my calorie limit in a day so my eating is fine. Just to give you a good idea I weight 233 @ 5'9. Any help would be appreciated thanks!!
