Photoshop edit

I have an an image that is attached and want the back ground copied so it is all the same , it is 36mb big and the jpeg will be transfered via we transfer and the edit needs to be done within 12 hours or sooner, the job should be returned in a psd file with the layer left open to edit to show your work , the background behind the two babys on the right have been completed and the texture should be copied to the rest of the image, detail is tail is required and high standard required only apply for the job if you can meet the deadline/ you should also have acess to zoom if we need to have a conversation.
