How hard is it (in delta-V terms) to launch a probe into orbit around Halley's Comet?

The orbit is obviously very eccentric; also inclined and retrograde. From the example of Ulysses, a suitable Jupiter flyby can put you into an orbit which is inclined, retrograde, and with aphelion at Jupiter, but I have no idea how hard it is then to raise aphelion and lower perihelion to match the comet.

It sounds the sort of thing that an orbit-designer would have done as an example at some stage, but I can't immediately find it on the Web.
