Hi, there. I HAVE EXPERIENCE and i'm NEGOTIABLE
I am the developer of SmartLabs, a romanian software for healthcare laboratories.
That software is developed using Delphi.
Anyway, i have a few years of experience using c#, so it wouldn't be a problem to make what you need.
Please provide some details about the lab machines you need to connect. Taking into account that this business (lab machines industry) is a worldwide industry, it's possible that i can help you pretty easy.
I we are lucky enough, i won't have to work too much for the money, and you'll get a cheap and fast solution.
Anyway, i am able to help you, even if i don't have the needed protocol implemented in Delphi.
Please contact me before awarding, i won't accept a job without discussing details.
