CMS 1500 to ANSI 837

Looking for c# or j# code that can create an ANSI X12N 837 version 4010A1 batched claim. We will supply a sample code CMS 1500 utility in j#, that would need to be altered to create the ANSI batch claim. We would like this completed as soon as possible. It should not be difficult for anyone who is comfortable with the ANSI 837 format.
