Import/Collect Data Feed + Desktop App (GUI, Databases, API)

Looking for a programmer that can help me create a desktop application that recieves data feeds from a couple of different independent sources (One source is for example JSON or XML. Not sure about the other and will take some digging around to figure out how to retrieve). The data is to be collected, sorted, mapped in the application and then compiled to XML and to be exported as a feed to other systems/websites. The desktop GUI should be divided into two different environments. Internal and External. The external environment is where data is to be collected (Every x minute) and sorted . Here I would need to be able to add new categories/nodes to help sorting progress and be able to add relevant data to internal environment. Example collect a pile of data from a source, break down the data in different categories and sorted in application. The internal environment is where I want to collect the data from the external environment I need for the xml file I want to export. Here I also need to be able to add new categories/nodes and then map this to corresponding nodes in external tree to automate the process. So it can be logged in outgoing XML feed. "Skills Required" Added some skills that I believe is useful. But I'd suppose that C Programming isn't needed if this is doable in another language. Same goes for any other skill. English speaking is required. Living in Sofia is an advantage. Contact me for further discussion!
