DIY-builder time investment — estimates range from "a weekend" to 190–400 hours; every source conflicted

Claim: Published estimates: a weekend (1–3 days) for a simple site; 10–40 hours including learning/troubleshooting (a DIY-vs-pro guide); 30–50+ hours including SEO/accessibility; one agency claims "190–400 hours" for full DIY competence.

Source: Mix of builder marketing, agency content, practitioner guides.

Confidence: Directional-Speculative.

Caveat — every source conflicted: Builders minimize (selling speed). Agencies maximize (selling alternative to DIY). There is NO reliable independent study isolating owner build/maintenance hours. Treat the entire range as conflicted.

Why this matters for Candid: Flag as a gap, not a finding. Any client-facing piece must state "no reliable independent data" and cite only the conflicted range with conflicts named. See R3 — Do not publish a DIY-builder time-investment number as fact.
