Query regarding market condition of 3D tv, LED tv, DSLR, laptop in Bangladesh?

Hi there:

I would like to know about the present market condition of 3D tv, LED tv, DSLR, laptop in Bangladesh? How much one can expect to make profit by importing from abroad and selling it in the local market. Lastly what is the difference of price of 3D & LED tv in the market and if any one bring it as a baggage. I am really looking forward for this business if it is profitable while living in Canada.

Any reply will be highly appreciated.

Thanks,
