For a single-engagement WordPress build the math runs different from a multi-developer team. One WP dev for a 4-week WooCommerce rebuild = 160 hours at $55/hr ≈ $8,800. Compare against a US WP agency typical site project ($25k–$60k) or an in-house hire ($150k/yr loaded plus a $15k ramp). Solo WP engagements pay back inside 60 days for sites under 100k monthly visits and single-plugin authoring work; once traffic crosses 500k/month and the editorial team needs concurrent block + plugin + ACF migrations, a 2-dev paired engagement becomes the right tier.
