Quoting for system development projects

I have been asked to assess a quote for a system development project and there’s not much to go on:
– project management $x
– system development $y

I would expect to see at least a breakdown of number of resources at $ per unit of time and probably split across:
– project management
– requirements analysis
– system design
– database design
– development
– validation
– implementation

What sort of detail do others give/expect out there?
