Read these as worked calculations

These are fictional project briefs evaluated by the SiteCost model, not completed projects, client invoices or observed market averages. The delivery factors change the amount; they do not measure provider quality. Additional requirements need their own quote.

($1,000 base + $1,100 features) × 1.4 design × 1 technology = $2,940 freelancer scenario

How will the lead reach the CRM?

Specify fields, required consent, duplicate handling, confirmation and how failed submissions are surfaced. Supply approved copy and brand assets before the build is priced.
