B&W speaker dealer

[Tanzania]

I am setting up a 7.1 system for my home.
Using Toshiba 65HX81 HD monitor with TSD-3000 HDTV tuner
I am purchasing Denon AVR 5803 receiver
I have a 20x18 room. My budget for speakers is $2000 (with subwoofer). What do you guys recommend? I am consering B&W, but don't know which models i can afford. I also need to know of any good reasonable-priced dealers. I like to watch movies and listen to music on them.

get 4 B&W 602s for each corner, then a cc6 for center, and a velodyn sub =). My dad uses 602s in each corner of his HT and they sound very nice. 602s also make awesome computer speakers =).
