blockchain.info's wallet also offers a "Second Password" option, which asks you to provide that second P/W before sending out any BTC.  I have used that, and it works just fine.

Both the Trezor and Ledger Nano (I own one of each) also use rudimentary (= good enough for me) 2FA both to get access as well as to send BTC out.  And I have used those as well, they both work just fine.

Coinbase offers this kind of feature, you can specify in which situations you require 2FA.
For example:

+1 for your signature campaign totals.. you have no clue what OP is asking. He needs a service, where you need to use 2FA before you send funds from your account. The 2FA at login with some

services has nothing to do with this need. Blockchain.info has 2FA at login, and it has a secondary password before you can send money. The problem with this is, once you logged in, you can change

that password. So it has little value, if your account is compromised. 

You are selling 3 Members accounts for 0.03 , Means one member account for 0.01 BTC. This is quite an high amount  considering the high value of bitcoins now. Anyways best of luck for your offer and auction.
