Cloud Pbx development

I am looking for an experienced developer to help me design and implement a full Cloud Pbx system with mobile application (example: 3CX). I have decided to use a multiple-server architecture, and I do require specific hardware and software solutions. I also have a deadline in mind, so this project needs to be completed quickly and efficiently. If you believe you are a fit for the job, and can help complete my project in a timely manner, please contact me. Thank you!
