Hope to get correction by a Native Speaker,thanks

 The followiing message  is my only hope that  my true words can lead to  knowing  me by the protential buyer overseas. Forging and casting buyers in particular.

Dear Sir/Madam ,

My name is Harry [ insert your surname], from China. My job is  that of a sales agent. I have engaged in foreign trade for nearly 30 years. In recent years, I have been engaged in  the export of Forging and Casting, so I am familiar with factory/ foundry and products as well. frankly, I am a liaison person, not a engineer, I know only particular products, where they  and where they are good. To be  technically  specific,  I think need to comunicate by details, drawings or other information for buyers and suppliers.

I think I am  like a linking bridge. I hope the buyers know the factory / foundry through the excellent products.  By approving factory / foundry and establishing  a long-term relationship of supply from that on.

I am honest and serious man. I am not only responsilble for my customers, but also for the factory / foundry. Before  any recommendation, I will carefully study a  factory / foundry and check whether it's appropriate, as to their technical capabilty and the level of production. So that my efforts result in satisfying both the seller and the buyer.
  I look forward to hearing from you and can assure you of my excellent service.
Yours sincerely ,
Harry [ insert your surname]
