PrimeGrid is currently sieving factorials using fsieve written by myself and Geoff Reynolds. They will eventually start a factorial search. I suggest that you team up with them. If you really, really want to do something on your own, then I recommend Ken Davis's MultiFactorial search.

PFGW will take an ABC file from any current sieving programs out there.
