What is the best way to convert more that 60 ETH to USD?

I’m working with a couple of generative NFT teams that need to convert ETH to USD. Someone told us that Coinbase isn’t good for handling that type of volume. Is that true? What is a better way to convert more than 60 ETH to USD?

Edit:

Thanks so much for all the input! It’s not because we don’t want to hold the ETH. The teams are raising money for charities and the charities need cash.
