There is no safe way to do this all at once in a crypto world. Even the safest exchanges like coinbase doesn't provide you with enough security to trust them with your eyes closed. They have known to "over do security" measures and keep your money in there for a long period of time even until a court order is released, a lot of people lost thousands of dollars on places like Coinbase.

Hence I think you can't exactly do this that quickly. However if you decide to slowly do it, you can just send small amounts of money to a place first, get a rating high, get the exchange to know you, give all your info and slowly you can increase the number, it may take months even a year to achieve all of it, probably even more but in the end that's the safest way.

There is no way for not using face to face exchange with someone or giving your KYC information for that amount of money, you have to either do one or the other. You can find an Bitcoin ATM machine but they will not have that much money in it.
