Help making separate programs communicate w/ each other-chiropractic clinic

I am looking for a talented freelancer to help me make separate programs communicate with one another at my chiropractic clinic. It needs to be real-time communication, so the information is instantly received in all parts of the system. In addition, the freelancer should be able to provide detailed project proposals in their application so I can get a better understanding of their experience and past work. The specific programs that need to communicate are x-ray imaging, patient database program and thermal imaging software. The goal is to input a file number into one place and have it distributed throughout the other programs, so I can effectively maximize efficiency. If this is something you think you're capable of doing, apply now!
