If Country Fair was a big hit, my suggestion is that you keep that idea and grow it into an anticipated annual event. Tweak it to remove the parts that didn't work so well last time and/or add something new to it.
A high school here has under 300 students. They have a carnival as their fundraiser each school year. They have not changed the theme in 15 years, they've just fine tuned it. Over time things got added or dropped, depending on what worked and what didn't, ideas and availability, etc. but the general event stayed the same. It remains popular and is an annual community event that spans 3 days over the weekend in September.
Some of the things they have are rides, games, food, raffles, silent auction that fills the gym, live entertainment, bake sale including home canned goods and fresh fruit/veg. It's like they cram a dozen fundraisers into one. They get the support and donations from local businesses too.
