Create Sync module between Filemaker and MYOB

PLEASE!!! If you do not know Claris Filemaker, JOSN API and MYOB API please don't think I can do this as is not a newbie task. Looking for someone to create a module to automate the sync between Filemaker and MYOB. File is running on a server and will be triggered by a Schedule script. Nothing is implemented in regards to the automation side of things. Everything already works with manually running the script's, However currently it will send or get everything, rather it look for things that have changed since last sync timestamp and just update those as to reduce server/network load. Further details in PDF as with sample of script from manual sync. IP Agreement will be required as software is licensed and not for redistribution.
