How can I find a distributor of wind turbine blades?

Hi, all
I am just wandering how to find a distributor of wind turbine blades. Situation like this, we company manufactures small wind turbine blades. At present, we have many customers at home, but a big zero for our market abroad. Does anyone works in this field? Or do you have friends engaged in wind energy products?
I would be appreciated if someone could give me suggestions.

Martha
