Photo enhancement

Hi, I have a special photo of 4 generations of the same family posing for a photo together. I want to present it in a nice frame but it looks pretty ugly right now. The background is of lots of wardrobes and there is an ugly brown carpet in the way too. I wonder if someone can turn this into something memorable for people to view for years to come?

I hope to provide more photo's to edit in the future.

Please could you let me know a fix cost for doing this. Many thanks.
