I need a Revit Expert

We want to make a Revit plug-in for our map-data. We have a online store www.e-torg.no where architects can buy map data - both 2D and 3D. They will get a zip-file delivery with different data formats. This zip-file must be possible to import through this plug-in. The plug-in must unzip the data and fetch relevant file formats to build a complete situation in Revit. Terrain, buildings, poles, trees ++++. We can deliver any 3D format in the zip-file. Current setup; IFC, DWG, DXF, 3DS, SKP.
