Create Balanced Image Collage in C#

Please note I need this in coming 2 days and budget is 100 dollar. Write a code that will take upto 10 images and create a balanced image collage in c#. The function/method will import the images and create a new jpg image, which will be the image collage. The function will accept width and height as parameters. For instance, if 300 is entered for the width and 500 is entered for the height, the final collage should be 300 by 500. The images should fill up the size of the final collage. It may not be possible to crop all images down to the same size, but as long as the end result looks balanced.
