The subcontract isn't ready, the start date is, and the main contractor has sent a letter asking us to get going.

The job is running on a quote, a few emails and goodwill, and something has now gone wrong.

The letter capped what we could spend, the job carried on, and now they say the cap is all we get.

The letter ran out weeks ago, the subcontract still isn't signed, and nobody has said anything.
