Photoshop of family photo

Hi, I need a family photo to be photoshopped so that everybody is smiling and looking at the camera - I have three or four photos that need to be combined, ideally!

Photo 1 is good apart from the old man at the back and the woman on the left. They are better in all the other photos.

Photo 2 is good apart from the man on the right (with the baby), he is best in photo 1.

Photo 3 is good apart from the young woman in the middle, she is better in all the other photos.

Is it possible to combine these to give photos 1, 2 and 3 with everybody looking at the camera and smiling (apart from the grandma, she is perfect in all three!)

Please reply and let me know your cost.

Many thanks

Ellie
