I'll look up a motor gearbox combination tomorrow, it's past my bedtime now. But about a 1 KW servo motor and a 500:1 gearbox would be about the right combination for your needs, and not expensive. You normally buy the gearbox and motor as separate pieces, but the motor just attaches to the gearbox, looks like all one unit when assembled.

Totally missed that point, I didn't read properly
Seems to be a more reasonable solution

Do you have any references to recommend?
