I need two Photoshopped images created

Hello,
I'd like to have 2 photographs of black-framed Wall Clocks edited to create 2 new images of Copper-framed wall clocks.

I have a high resolution picture of a sister-wall clock that has a Copper frame on it. You can take this image (from face on a white background) and cut out the frame and put it on two other images I have of the different styled black-framed clock.

I'd like the images delivered in the highest resolution possible. I'll then be using them (compressed) for ecommerce. The user should not be able to tell that the created Copper-framed images were not photographed at the same time as the black-framed clocks

Final note - I need the final two images staying the same shape/proportions as the current image of the Copper clock.

Hope that this is clear but I can provide further instructions if not.

Thanks,

Rob
