Try Mullers Method.  It is a fairly popular algorithm used to find complex
roots of polynomials.  I believe it works given complex coefficients, but
I'm not sure, it's been a while.

You should be able to find a solution to your problem by looking in any
good book on numerical analysis.  The one I have is "Elementary Numerical
Analysis" by S. Conte and C. de Boor.  This book may be especially helpful
if you're doing the work on a computer, since the method is given in
algorithmic form.  One downfall is that you may have to do a fair amount
of scanning of preceding chapters in order to understand their notations
(divided differences, for example).  Hope this helps.
