Background removal and slight touch ups on 62 photographs

I have 62 product photos that have already been taken, all on a whitish background.

As normal there are hints on grey plus some dust etc on the background hence the background needs changing to pure white so that it can fit in with our catalogue. The products are relatively straight forward (door handles etc) and shouldn't cause any major issues. Ideally I would like the shadow to remain to make it look natural - if this causes issues then we can discuss.

I am looking to get all 62 images complete within the week (with images drip fed on completion) to meet with other deadlines. This is likely to be recurring work so I am looking for someone who can deliver good quality images on a long term basis.

PS: Images need to come back with the original file names and resolutions.
