C# Forms application Barcode Reader / Creator

Need someone to integrate a barcode scanner into my software package, the barcode reader would need to be running as an interface or something like that and would need to monitor if the form is running and a barcode is scanned it would add it to a datagridview and add it to the sql database i am using. I have developed the software myself so far but do not understand all about barcodes. I assume this would be a rather simple job for a developer with experience and dont think it would be very complex. I look forward to discussing the project more in detail upon getting your bid
