Product Images standartization

We need to "retouch" 76 product images in order to convert them to a standard size with a standard background and standard quality for an online shop we are upgrading.

We are looking for a quick designer for the job.

Example images are:
http://cdn.shopify.com/s/files/1/0206/1866/products/07-0101-01_1.jpg?289
http://cdn.shopify.com/s/files/1/0206/1866/products/bausch-lomb-renu-multiplus-fraicheur-confort-3-360-ml_14032012153213.jpg?289
http://cdn.shopify.com/s/files/1/0206/1866/products/Sterilid_products_quarter_size.jpg?289

Before the work starts we would like to discuss the chosen size, background color and quality that was chosen.

Thank you,
Itamar.
