Basic Batch Editing of Images (approx 100)

I have raw images of mirrors i need editing. I need the sizes reducing for online, a watermark putting in it, the \'reflection\' in the glass changing from a warehouse image to a living room image and a soft border putting round each image. please see attached files as an example. i would like a quote per image please as this will be an ongoing project with an initial 50-100 images then a batch of 20-30 each week - visit www.exclusivemirrors.co.uk for examples
