The engine underneath this is proven and running: it answers an Australian firm's customers from the firm's own documents, with the source shown. Pointing that same engine at your team's internal files is the same parts in a new shape, a build I would do for you rather than one already running for a team.
If this is the one costing you the most, that is where we would start. Twenty minutes to talk it through.
