This. Download yafu or ecm.py, either of which would orchestrate the ECM stages. In yafu's case, if it finds enough factors in ECM to get it into NFS range (IIRC the record is around the 250-digit range, and for a solo effort it's realistically under 200 without a massive amount of hardware), it can run that too using GGNFS and msieve.
