A small program to control AI to export PNG imges

I want someone to write a small C# / C++ program to communicate with both of ArcGis map file and illustrator for map image exporting. Here's my specific requirements: 1. Utilize ArcGis SDK to put MXD file ( ArcGis map file) to export a PDF file with 300 dpi 2. Execute illustrator adapter to fetch that PDF file and export a PNG file with 150 dpi That's all, so simply.
