Five of them: a quote with no written detail on what is and is not included; a very short promised timeline offered without questions about the details; refusal to give you hosting, domain, and repository access in your own name; no live project you can open right now; and a demand for full payment upfront. Any one alone may be justified, but two together is reason enough to stop and reconsider.
