Options for OTC selling large BTC amounts (5,000, 10,000, 20,000)

[a-m]

I would like to compile a list of options to sell large amounts of BTC off exchanges, so they don't effect the market price.
My current state of knowledge is that there are brokers for OTC (over the counter) deals, who connect buyer and seller directly.

Do you have any specific names of brokers and services that offer OTC?

Thank you.
