We are a B2B company that sells toner supplies and parts online.  We are needing to build a new ecommerce platform and are in the process of talking to several Marketing and Web Development companies.  I am looking to hire a consultant who can teach me about Big Commerce so I can have a better understanding of the platform to determine if its the correct platform for us.  Some of the requirements we have for the new site are:

- 7,000+ items w/images
- Integration to our ERP, SAP Business One
- Google approved setup
- Order forms for users that can also be managed from an admin portal by my employees for the customer
- Robust search
- Master/Sub user hierarchy with robust authorizations
- Related items capabilities (device A has item A, B and C that goes into it)
- Ability for customers to add a PO# at checkout
- Customizable order confirmation emails to users
- Saved cards
- Ecommerce cart approvals (sub user creates, master user approves)
