Developer for Twilio applicaton - longterm ongoing work

I need someone to customize and implement the following Twilio script for me:
----------

The guide is available in the following programming languages: Ruby, PHP, C#, Java, Node.js, Python.

Please see the following illustration for visual explanation of how the finished script will work: ----------

I also need a SIMPLE dashboard where users can login and connect their Twilio phone number, change settings and access call reports.

Previous work in Twilio will be a HUGE plus.

After the initial development I will need further development, support and debugging on an ongoing part time basis 5-10 hours per week, more if needed.

It's a plus if you're Cebu based as I'm here until May.

PS: Make sure to answer if you have previous experience with Twilio in your application.
