Software programmer

Hello, i have a small piece of software i am looking to replace and bring upto date with a new take on the idea. my current software is an interface between our company management system and my assembly line, the software simply draws data from our management system and inputs the data to a SQL server. it will then use this server as a lookup, as when we scan a job order barcode, it will identify the required data to output and load a job to our PLC via 3 digit ASCII text. the only other function the software has is, when it recieves a signal via serial cable from one of other pieces of equipment, it will trigger a barcode to print. i have software flowcharts and info available for you. i do not believe the project to be huge, however, it will need some experience with machine interface for the signaling i am using. please dont hesitate to get in touch if you are interested. Kind Regards Jack Mercer
