Go buy a wattage meter ($25-$30) and measure what you're using. I think you'll find you don't really need that much capacity. 2000W will not run safely on a standard 15A wall socket. You'd need a 20A wall socket (with the non-parallel blades on the plug) or something similar for 30A etc. Hence, you'll not find a simple surge protector that fills the bill.
Surge protectors don't protect the power you draw; they protect the equipment from a spike that is on the outside. Hence, you really want to get something that can stop the surge at whatever you can draw off a 15A wall socket. Most standard surge suppressors will do that.
If you want a UPS with surge suppression and/or power conditioning, then you have to worry about satisfying the actual power draw while running on battery etc. However, these will still be satisfied for about $200 for just backup + surge, not $2000. Power conditioning will cost more.
That 4000W surge suppressor I pointed to was just to show that something over 2000W was easy to find; it was not a recommendation.
