Jeff: Institute of Internal Auditors at
www.theiia.org If you join, they have a mag they publish (online and paper) with sample audit programs. For an extra $40 you can also join the financial services group - - - more newsletters with sample audits!
And there's the networking aspect - - - trading with your peers.
I bought a manual of bank audits, too. Same thing.....just tweaked them for our shop. It came from RIA. Even has a disk with workpapers. It was a good investment for starting from scratch.
Good luck to you.
