Photo Modification and Enlargement

I'm looking for an experienced photo editor who can professionally alter a photo for me. The job involves: - Adding another couple to the particular photograph - Possible enlargement of people while maintaining a 5x7 dimension - The finished work should be in JPEG format Experience in Adobe Photoshop or similar photo-editing software will come handy. Ideally, you should have a good eye for detail to ensure the added couple blends perfectly with the original photo. No additional filters or effects are required. Please only bid if you can perform these changes while maintaining high-resolution quality.
