Most Reliable OTC Platform?

Hi everyone, I'm planning to convert a large amount of Bitcoin into Monero. It's a seven-figure transaction, so I’m being extra careful and want to make sure I do this the right way. I'm hoping to hear from people who’ve done large swaps like this before or know reliable OTC desks that focus on privacy and security.

There’s no rush on my end; just trying to gather solid options and make sure everything is safe and well-handled. If you have any suggestions or personal experiences, feel free to drop a comment or send me a message. Really appreciate any help!
