Create a 3D CAD version of a house out of 2D plans - use my software (or your own) export as .DXF file

I have 2D plans of a house. Now I need someone, who transforms it in a .dxf file so I can import it in my software (CadVilla Professional). I can lend you a copy of the program (you have to give it back /delete it afterwards!)
Here you can see the quick 2D to 3D copy-mode: https://www.youtube.com/watch?v=9CoaP5ZqXoY.
