Exchangers do this,
http://technocashier.com/ has a pay any Visa/MC service no idea what it costs. Maybe if you did it all the time could get a cheap rate. Takes 5-7 days.
Or sign up to some Visa payment gateway, depends on how many transfers per day you're making
http://www.nxsystemsinc.com/03_payanycard.htmlCould also sell bitcoins to Liqpay, then send it another card. That person then signs up to liqpay to claim the funds but again takes 5-7 days and doesn't work with non USD/EUR/UAH cards.
Could use eCoin.cc to transfer them internally and they withdraw from their own ecoin debit card for $2
I used ICICI bank in Canada to do this and it worked, they have US branches too
