Hi Brian, take a look at the Siemens motor and open source controller used in the second electric incarnation of Damien's BMW 8 Series (here).Any advice and direction would be appreciated.
The Siemens motors were used in the Ford Transit conversions developed by Azure Dynamic ("AZD") and are often sold on eBay at low cost.
For batteries I'd suggest you take a look at the Nissan Leaf Modules and BMS. Wolf has reverse engineered the BMS and is using it in his truck (here).
