I would have suggested a motorized setup except that constraint No2 would rule out a motor.
You will be limiting the amount of receivable satellites if you go down the mulit LNB + Switches route. The other option would be to have a second motorized dish, but you say you dont want that either.
EDIT:
Have a look here
Multifeed WFT-90 some modification done
Thats a pretty fancy setup, you could have a more simple sytem with a few offset LNBs once you decide what sats you want to receive. I dont watch foriegn language channels so cant advise you on that.
You'd also need a decent size dish for this kind of setup.
