Hello!
I've worked with Delphi and client/server applications for a long time (and Delphi 6 too), I've made complex hardware/software solutions and that's why I'm going to help you with this project. I have specific experience and understanding on how to do this project.
If you choose me, I can help you deliver the best solution and lower costs.
I offer to do it on Delphi 2006 or Delphi XE7
Sincerely yours,
Vitaliy
