Wow...You are very talented!
Many years ago, before I got into flowers, before kids, before marriage, etc... to make extra money I carved into pumpkins - the logos of each store on our Main Street. Once I got one store to bite, they all had to bite. I put an extra $1000 in my pocket for a rainy day.
You need to market your talents to all the business establishments for Halloween. I bet you'd make a pretty penny.
