CIBC Positive Pay

I have a client using Sage 50 Quantum and would like to use CIBC Positive Pay.  It is a very detailed format, with specific character spacing, that the CSV file has to be in.

Does anyone have any experience in creating this file easily?  I was thinking of possibly using Sage BI.

The client of course would like this ASAP so any assistance would be appreciated!  :)

Thanks!
