Can you informs me the righteous buyers name of Canada & USA. I want to export radymade garments from Bangladesh? Answers: That's not how it works, you can't

Answers:
That's not how it works, you can't just bring back buyers to buy your products, there's more than just a couple accurate buyers. It all depends on what you proposition, styles and whatnot.

Try looking at http://www.alibaba.com

But also do not forget the Bangladeshi market. Don't walk after a foreign market you don't know very well if there's a market right within front of you.
