Resize 20 Images for use in website

Hi have 20 images that I require (2) different file sizes for use in a website, a preview image and enlarged image.

This is extremely URGENT. Files are in my dropbox. i will give the sizes of the images to the the winning bidder.

I require these files no LATER that 6am Melbourne Australia time - 1st March.

If you cannot complete this project, please don't bid.

Thanks heaps. cheers
