Website images, collection and optimising.

Hi

I need at least 2 images (one fully spec'd machine & one minimally spec'd) sourced and downloaded. For business photocopiers/printers for each of the about 850 products from an list I have (That's a total of 1700 images) all images taken from the web.

All images need to be:
Downloaded above 800 X 800 dpi (higher the better)
Free from watermarks
Free from any identifying marks
Not digitally marked
Ideally from the manufactures site
No copyright marks or statements.
Have a white or clear background.

I need them to be:
Files named the same as the product name (put in to two folders 1,2)
Returned completed within 3 weeks
All images need to be 800 x 800 ppi

To be all the same size and quality (optimised quality v file size)
Must be completed by yourself or your organisation.
All originals kept and transferred along with amended files.
All transferred to developer upon completion.
