Looking for a programmer pros, developing a system on Framework connection by IPAs to services

Hello!

I am looking for a reliable programmer who is ready to be in touch and delve, to work closely on the project, because the task is difficult, interesting and urgent) For those who are already loaded in other projects this task will not fit, because there is no time to wait. Over the weekend, you need to at least study the task, and possibly get started.

In short, the point of the problem is this:
There is a website that collects leads in the writing system on a separate server. You will need to write a separate system on any stable Framework, from which will go requests on API (instruction attached) with a third-party service in conjunction with our self-written system - requests to check takes/ pull up data depending on the conditions and transmit by IPA to the site live.

The task will be broken down into several stages of work, payment strictly on the performance of a certain stage of work. Ideal, but not necessarily, accommodation in Moscow or the region to be able to meet to discuss the details for greater productivity. I will provide the most complete information for all stages of the work.
