For this room size, you need to go in for bookshelf only HT system as FS will be killing in here...
Secondly, as per your budget is low, prefer building your HT over a period, rather than getting some HTiB crap...
You can look in for some options like Q Acoustics, Wharfedale, Paradigm, etc...
for building your system slowly and gradually, like getting an AVR and Bookshelfs and cables first...Then gradually adding the Center, the Rears and the Subwoofer, over a period of time...so that at the end of the setup, you will have a dedicated system for your dedicated HT Room...
Even though if you are really keen on getting all the speakers at one shot you can buy Polk Audio basic setup without sub...So after discount and all, it should be approx. Rs.55-60K including amp and cables...
But, dont at all go in for ProFx speakers, they are even worse than the HTiBs...
