There was a vendor; there is a half-finished system, a slipping deadline and eroding trust. We do not start from zero: we assess what can be saved, and we finish it.
We review the code, the database, the documentation (if any). You get a written status report: what is salvageable, what is not, what is missing.
No "we will see": a proposal split into milestones with fixed prices and committed dates.
Trust is our burden, not a promise: we deliver tangible, working results in the first two weeks.
The first step is a fixed-price assessment: we review what exists and tell you in writing what can be done, for how much, by when. Then you decide.
