Yes indeed, please use escrow for these transactions. 2 to 5 BTC daily is the kind of transaction you definitely will want to use escrow for. Trusted and reputable escrow members on this site. Agree and arrange with the escrow directly on their official pages, channels or emails.

SWIFT T/T is a good way to pay but I would suggest not adding anything about bitcoin on field 70 of the MT103 reference box. Even if both the sender's and receiver's banks are relaxed about bitcoin transactions, there is always a chance that the correspondent or intermediary bank relaying the payment might reject bitcoin-related payments and either reverse it or delay the transmission. This risk is heightened when large transactions are being transferred. To make it a hassle-free wire, don't mention bitcoin.
