SOAP XML integration Khaos Control/Magento

We need out new Magento website integrated with our back office solution via SOAP XML files.

We are a stock control and mail order system, which allows us to manage our stock, enter orders, process and review customer requests and a range of CRM functions. The system has a SOAP-based API which enables orders to be placed directly into the system and to return CRM information about customers and other activities. The API uses SOAP to interact with the system.

The data that needs to be integrated:

Import
Sales Order(s)

Export (from Khaos Control)
[1] Sales Order Status [Basic]
[2] Stock Items that have changed List
[2][1] Stock Item Detail
[1] Stock Status
[1] Price List(s)
[1] Keycodes

We need an experienced developer to do this job, as KhaosControl only provide 16 hours of handholding service, after this, an hourly rate is applicable.

Job has to be done beginning of September.
