Can I create a business account on any of the major exchanges? (coinbase, kraken, river, gemini, etc)

If my small business LLC has a profits at the end of the year, I would typically keep them in a high yield savings account until I figure out how I want to reinvest or pay down debt or take a distribution. But now I think I would like to hold that money in Bitcoin until I can decide what to do with it or if I just want to hold it long term. Does anyone know what exchange or company I should contact for something like this? I would need to establish an account as an LLC instead of an individual so how would that work with all the KYC/AML nonsense?
