Oh you have solved my problem, I want to sell it. And because you are known to me through rediff Q&A I will give you a big discount. Meet me at 12 o' clock near the Qutub Minar to fix the deal.

You cannot buy qutub minar. i dont think that archaeological society of india will sell it to you
and even if you buy you cannot compete with burj dubai for 2 reasons
1. burj dubai is a building and qutub minar is a monument
2. qutub is much smaller than burj dubai
