A quote that comes back within a day should be treated as a bad sign. A competent team returns a list of questions: about who owns the data and what happens on failure.

Be wary of a gap between the engineers on the sales call and the developers actually assigned. Insist on named engineers in the statement of work, with wording that requires notice before anyone is swapped. A vendor that talks only about abstract roles and will not commit to individuals is reserving its own flexibility at your cost.
Ask for commit-level visibility from the start. A partner that shows a build only at the end of each phase is asking you to accept a black box. Daily commits tell you who is really on the project far better than a weekly report.

Unclear written communication in the early emails will not improve once the work starts.
