Photoshop Wedding Photos

There are some photos from our wedding that we would like to be photoshopped and fixed. I forgot to write down to get a photo of me, my sister and mom so I would need to photoshop my sister in with a photo of me and my mom. Me and my husband were in a room and in the background a strip was missing on half of the wall needing it to be photoshopped. There are photos of my husband up against a tree, there are some weeds in from of him. We would like the weeds to be photoshopped out.
