OTA Middleware (open travel alliance)

Please ONLY apply if you have relevant experience and are a developer.
NO; I don't want a team thanks.
NO; I don't want to Skype to discuss it more.
NO; I don't wish to 'partner' with you on future collaborations.

Ok, sorry real people for that ugly disclaimer, I get many boilerplate responses. I am looking for a can do developer, who is going to be a coder to do this task for me.


General information for the business:
Integration work for existing online travel agent software
Description of every module:
This is an integration module to connect OTA (Open Travel Alliance) providers to our own Propriety system.

For the purposes of simplicity and to speed the development we will create a new ASP.NET MVC Application that will contain the framework that we implement on the client side. As it has to be merged with our current code base this app will be in MVC5 rather than Core. Using Automapper, Unity and EF. We are building this now to give you the framework and patterns all done.

Description of requirements/functionality:
There are several providers, all using a mixture of different releases of the OTA Specification, but the common methods to be implemented are;

OTA_HotelAvailRQ/RS
OTA_HotelSearchRQ/RS
OTA_HotelResRQ/RS
OTA_HotelResModifyRQ/RS
OTA_HotelDescriptiveInfoRQ/RS
OTA_CancelRQ/RS
OTA_PingRQ/RS
OTA_ReadRQ/OTA_HotelResRS

Your task will be to create a repository type pattern that implements these methods and then maps the results to our Propriety system. So it will be MVVM is the expectation and use Automapper to control those. The reason for this is that there are several versions of OTA that we need to implement. Without knowing the exact specifics if there are differences then we will have a different VM for each schema and then map that to our own VM then save or update. Pretty simple. But attention to detail is critical.

There is a Part 2, in which we will implement a subset of the Rental Car OTA spec. But I will add that as an extension to this project or new project.
CMS and Admin requirements: There will be some User Interface to this application to enable the management and testing of these methods or indeed manual use of them.

This will enable the system (test user) to;

a) Search for new Hotels
b) Map hotel results to existing hotel or add a new hotel (of course this can be automated but we may also wish to do it manually).
b.1) Map amenities,descriptions and potentially the lookup data to our existing data (this is low priority, we may not implement)
c) Call each of the methods to book, amend, cancel

As noted - we will provide a new MVC app with the base framework and patterns and a SQL Database with our lookup data.
Specific technologies required: C#, ASP.NET, MVC5, Automapper, Unity, SQL, XML, REST, JSON
OS requirements: Windows
Extra notes:

As it involves our Customer Data and our Customers Supplier Data this is all confidential to them and you will be required not only to sign an NDA but give your honest commitment to the security and integrity of their data and the application. Please acknowledge this in your message.

Only Developers who are proficient in C#, Linq, MVC need apply. You do not need to know the OTA specification, it is just an XML Request / Response Pattern which you will learn and understand quickly.

Please don't send any generic proposals for template type replies - I will just ignore and delete those.

Happy for hourly and/or fixed price. I am a Microsoft Technologies developer and can do this myself but need help due to time constraints. I will give you sample code and my framework / patterns / practices.

Please demonstrate to me that you have read this fully and have some understanding of what it is we are trying to achieve, Thanks, Steve.
