424368 Building EDI in-house

I need to build EDI in-house so I can get rid of an EDI service provider. For this project I need an experienced EDI programmer who has developed EDI in house previously (reference needed). My EDI should be compatible with most of the EDI standards as we have many different customers as well as vendors using different standards. Anyone with previous experience in developing EDI using different standards such as AS2, X12, EDI mapping, Scripting, etc. please contact. Looking forward :)
