COntract template for Engineering firm

One of my largest Clients, the Florida Department of Environmental Protection, has a specific format that each proposal/contract has to be in. Each phase must be a Subtask starting with 1 with a manhour table and general language for each subtask. Everything is summarized and totaled at the end of each subtask and all subtasks are summarized and totaled at the end of the document. Routinely, the Client eliminates certain subtasks depending on the complexity of the project. I need a template that includes simple spread sheets for each subtask and will automatically adjust references.
