ODL TO ATHEX FIX SERVER 4.4 PROTOCOL (STOCKMARKET SOFTWARE)

I am looking for a freelancer to help me implement a ODL to ATHEX FIX Server 4.4 Protocol. This is a stockmarket software project and it needs to be tested. The type of testing I need is Functional Testing, as I will also require live data integration within the testing process. A timeframe is important to this project, so I need the testing to be completed within the given deadline.
