Banquest Event Template in google sheets

I am looking for a Banquet Event Template in Google Sheets that can be used for any kind of catering event. The ideal candidate should have experience in designing templates for event planning. The template should include options for tracking the number of guests, menu planning, and budgets. As the number of guests varies, it would be great if the template could automatically adjust to accommodate the changes. There is no specific color scheme or theme required for the template, as it will be used for multiple events. However, the template should be easy to read and visually appealing. The candidate should also be able to provide ongoing support for any updates or changes that may be required.
