Photoshop retouching/illustration

I photograph couples and put them into created backgrounds using photoshop. The final image are a mix of new photography and stock backgrounds (that I provide). The final composition should look realistic and stylized (like a movie poster or book cover). I need someone to help build these images in photoshop and provide me with a layered PSD file. Please let me know your price per image and provide a portfolio with similar work. ****I will ignore msg from artist who's portfolio does not match what I need created.
