Fix family photo

Took family photo recently with myself and my husband, my kids and grandkids. We have several shots, and of course something is a little off in each of them. Would like to have one photo where everybody looks their best. Have over 2 dozen photos altogether with different family groups and the whole group that could be used to make a composite. I can share the folder in Dropbox. We have NEF and JPG files for each image.

Need as soon as possible, was supposed to be a Christmas gift. Please let me know if you'd have any other questions. If interested, please let me know where i can view something similar you've done.

Thanks so much!
