Photoshop editing - product colour changes

I am looking for an experienced Photoshop user to edit/recolour a number of product images to be used on our website. The first two images show the product in it's natural/original finish but we now offer the product in 7 new colours (the 3rd photo shows the actual product in one of our coloured variation). I am keen to know if someone can edit original images so we can display the coloured products on our website. Before accepting an offer for the series I will require an Hourlie to edit the original image to reflect the colour displayed in the 3rd image as an initial trial so that I'm confident of the colouring of the edit. Any questions please ask.
Kind regards,
Russell Lambert
