I need a professional invitation caricature and scene image

Design details: I am looking to have a caricature image with scene designed. I would like the caricatures to look like the provided image of us and dog. I would like the scene and characters to look similar in quality to provided invitation example. I would like a large moon at the top center (with dusk sky) with river below reflecting moon and moon shining onto caricatures that are standing on a forefront bridge with male character proposing to female caricature. Dog would be sitting next to couple looking up towards them. In far background to the right would be the Disney Cinderella castle with fireworks above. Looking for CUSTOM WORK ONLY. No pasting provided images into the design. Looking for actual caricature artist to create the characters and scene. Willing to pay a little extra if you can provide a sample of what this would look like with our actual faces when you submit your proposal.
Ideas for the visual style: See attached invitation example
