Civil Register in New York

I am looking for someone who personally goes to look for a literal birth certificate at the Civil Registry of New York, USA with the data that I will provide because online service is very late. Then after getting it, you´ll send it by postal mail to an address in Madrid. The payment is 60 USD for this personal search service, but if you locate it and get it, I will give you 20 USD more when you send it to me to Monterrey, México by a selected postal mail. The payment for the shipment is additional.
