[AccessD] OT: Does anyone have decent Quickbooks chops? I'm in a bind.

Here's the deal.  One of my projects requires Invoice and InvoiceLine data to be pulled out of a SQL Server database and pushed into Quickbooks.  The client wants it seamless, so I've been reading up on QBFC and QBXML to make it happen.

A month later, I am nowhere.  I even joined the Intuit Developer Network, and I'm finding the documentation to be useless, the developer forums to be useless, and the lightly-commented sample code to be a game of "guess the object model", with numerous things in the sample code that are not in the SDK documentation.

I need help.  And I can't seem to find anyone who has done this before.

Does anyone here have decent chops with QBFC or QBXML?
