465923 Image Resizing

I have 381 images that are various dimensions. I need to have them all resized. The exact task is 3 things: 1. Create a duplicate image (same dimensions as original) with filename as [login to view URL] 2. Create a copy image that is 250 pixels in width, keeping the same aspect ratio. This file should be named [login to view URL] 3. Create a copy image that is 150 pixels in width, keeping the same aspect ratio. This file should be named [login to view URL] I would like to have this completed within 2 days from the start, and I'm looking to hire quickly. Once a bid is chosen, I will give you FTP access to gain access to the images.
