Gold making tips?

Does anyone have any solid gold-making tips? Because I have a vision for a house in my mind and I've calculated I'll need 114,850 Gold (for the layout). It took me about 2 days to raise 25,000 for the Grand Harvest House, and I was mainly selling bugs and fish I had been catching. So I was wondering if there were any more efficient (and quicker) ways I could make gold, or if I really just need to get on my grind 😭
