I just start a home base business a month ago .I would like to have
some helpful links that can help me purchase some items from then.
Please give me address,phone numbers, email and the direct ligne of
the sales person. Thank you!

A few suggestions:

1. The term "overseas" has no meaning unless we know your nation of residence.

2. When locating suppliers, it is helpful to know the approximate
quantities involved. Will a typical order involve thousands of items,
or hundreds, or a dozen?

3. A $2.50 price might be appropriate for a simple research project
that required five or ten minutes of work, but I doubt that you'll get
a satisfactory response to this kind of question at such a low price.
I suggest that you review the Google Answers pricing guidelines:

I hope that you are not asking about sources for counterfeit/pirate products.
