Choosing the right gear system and motor for Robot

Hi there, I’m looking for a motor that has very high torque low speed. Power usage around 20W. RPM around 7.5rpm. Initial motor needs to on the smaller lighter side, so a high ratio gearbox setup will likely be required. The max torque will be around 35Nm and will be intermittent. The intention is to also attach to a worm gear to provide a mechanical brake, and remove back drivability. Ideally, the motor would be double shafted also. Do you know of anything that would be suitable? Thankyou

Thank you very much! The planetary Gearmotor looks ideal. Do you know if this is back drivable? Ideally, I need the motor to be able to brake without a constant power supply. originally I had thought a worm gear attached could provide this, but are there any worm gears on the site compatible with this gearbox? If not, how can I produce this nonback drivability? Thank you.
