Where can I find yo-yo string manufacturers in Mexico?

I need to know who provides string to certain retailers and yoyo
manufacturers here in the states.

If there are multiple yoyo string manufacturers in Mexico, then I
would like a list of them.

I need the phone number, contact person, address, fax number, and
company name of the company that produces the yoyo string.

I need a price list of different types of string that they manufacture
- colors / fabric mix.
