The standard advice is not to do the Roth conversion unless you have the funds to pay the taxes already in hand...
Any way you can stash the cash in a savings account, building it up so you do have it by Apr. 15th, 2014?
Conversions need to be done by Dec 31 of the year you are doing it. For 2013 tax year, this is 12/31/2013.

Good to see you back, I was starting to miss your incisive commentary!
