It depends on scope. A focused website or small automation starts around $1,500–$5,000. Full custom web/mobile apps with backend typically range from $8,000–$30,000+. We always provide a clear fixed-price quote before starting.
A landing site or simple tool: 1–3 weeks. A full web app or mobile app: 6–16 weeks. We work in milestones so you see progress every week, not just at the end.
