Yes, you got it right , I need to know a location (website) from where I can find information on buyers of items of specific niche. Information like buyer details or the count as well for a country/world over a month/year period would help in planning an eCommerce move considerably ?

Can anyone help?

You mean like a demographic, I don' think this kind of data is easy to be found freely on the Internet.
But you may try your luck at Nielson (paid research data)
