I can recommend a good, relatively inexpensive accountant who's happy to do stuff by phone/fax/email/etc - call me, if you'd like a reference (as I download my Quickbooks file via FTP frm their machine to mine).

Yep, the IRS can drive you out of your mind very quickly :-)

IIRC, You would just send in the 1st quarter payment, and remember your next one is due June 15.
