359340 Castle image design

I need a castle similar to this one or this one fixed and finished. The picture of the castle I have included needs to me a much lighter gray and it needs to have all the individual bricks showing that make up the castle. Also the image is a very poor resolution and I would like the res to be 300dpi and the size to be 30inches long. I would like the file in either .ai or .cdw I am Using this for a sign for a new mall operation "Murano Castle" if you could incorporate the company name into the image that would be great, using a clean to read font.
