Alter two photographs

We want two photographs photoshopped to feature the words 68,000 and Remember. We will provide the original photographs One photograph is of the Hollywood sign in Los Angeles. “68,000” and “REMEMBER” must replace “HOLLYWOOD” in the same style as the original sign (white letters that are constructed) so that it looks like the sign actually says 68,000 REMEMBER. The word “REMEMBER” must be underneath “68,000” The second photograph is of Mount Rushmore where 4 American Presidents are carved into the side of a cliff. In this image we want the words "68,000" and "Remember" included in the photo so that it looks like they were carved or chiseled into the side of the cliff. Final product must be the adjusted photographs as a large images in jpg or png format.
