Your starting point should be the "Nonbank Financial Institutions - Overview" section of the FFIEC BSA/AML Examination Manual. While you won't find a checklist, you will find guidance as to the risk factors and risk mitigation activities. Since the NBFIs may run the gamut of a little to a lot of risk, it would be hard to determine the time involved until you've got some real cases with which to analyze.
