You will need at minimum 3000/4000 watt generator, but the best way to accomplish this is with 2-2000 watt genny's that are connected together.
This will give you the option of using just one or both as needed, & makes it easy to move around. They are about 45# each.
In consideration of cost, I recommend Champion. They are a very good product, dependable, great customer service, & parts are easy to find.
