My taxes were professionally prepared, confirmed by IRS, with a funds
transfer date of April 8, 2005 directly into my checking.  As of March
25, 2005, I have time sensitive, due and payable commitments of
$2,000.00, as well as an unexpected dental emergency. (I have never
had a cavity).  Can you provide any sources for a $3,000.00 immediate
loan?

Sure ... Stick it on a Credit Card.

I second the recommendation to put it on a credit card.  If your limit
isn't high enough, call them and ask.  Interest rates on "refund
anticipation loans" are always very high on the ones I have seen
advertised.

Another option is to call your bank and ask for a short term loan. 
Banks give out loans for more than just cars and houses.  Tell them
about the dental issue, and also whatever the other issue may be if it
isn't too detrimental to your case.  If your credit isn't bad you
ought to be able to get at least part of the loan for the dental work.
