Need an exe file to import images in a folder as background image in new powerpoint presentation.

I have a folder with x number of images (10, 20, 100, 200, etc). I need an exe file, that will take folder name in input. Once I hit submit button that will read - Go Knight, it will create a new powerpoint presentation (ppt) file in that folder, and create as many pages as images. It will also set each image as a background image in the ppt. Not insert the image, but set it as the background image. Attached are 2 images for your reference. Put them in one folder, make the exe and when I hit Go Knight button, it will create a ppt with 2 slides and each image will be the background of the two slides. Slide 1 will have the 1st image, Slide 2 will have the 2nd image AS BACKGROUND IMAGE. I want to get bids from you only if you can do it, if you have a similar app, show me. Let me know how soon can you get it done. This is for my existing client. Thanks
