I need a menu designed

We just purchased a business and the previous owners don't have access to the original graphics for the menu. I think it's time the menus are updated anyways but I don't want them to look homemade. We are a soda and cookie shop looking for a clean modern take on our current menu. These menu graphics would be for the drive thru and in-store digital display menus. We change flavors of the month each month so I'd need ownership of the illustrator files.
