Need a Photoshop expert for product design

We are looking to hire a Photoshop expert for some product design. We already have the product photography on a white background, and we would like to put it on a nice aesthetic background and make it look really neat and professional. The photos will be used on our landing page and on PDF presentations. We can provide some examples of how we want the work to be done. IMPORTANT: do not apply without a relevant portfolio.
