Do please contact your local planning and zoning office, to learn what permits are required, if this is actually allowed in your neighborhood, under what regulations.
Also definitely get advice on what health and safety requirements required, including business insurance, power, water and sewer hookups. Are there any emergency needs for public safety that the municipality or county require, and any taxes to be collected. Any time exchange of money is involved, it gets complicated. Best of luck ~ enjoy the events, and the marvelous Spring weather!
