Cost + timeline + credentials, what does a Magento build cost for hair extensions?

Realistic ranges for a hair extension / wig brand at $500k, $10M GMV:

• Magento + Hyvä build / migration: $25k, $80k. Hair-specific scope adds: color matching matrix setup ($5k, $10k), color-matching quiz ($4k, $8k), B2B salon portal with license verification ($6k, $15k), medical-wig FSA/HSA channel ($4k, $8k), subscription engine wiring ($3k, $6k), virtual try-on integration ($2k, $4k), customs / multi-region tax wiring ($3k, $8k).
• Timeline: 8-14 weeks for a typical mid-market hair retailer. Faster (6 weeks) for pure DTC with limited shade range; longer (16-24 weeks) for full B2B salon + medical-wig + multi-region scope.
• Audit only: $499 fixed-fee, 5 business days, ~20h @ $25/hr. Covers shade matrix audit, B2B portal readiness, medical-wig coding, subscription engine review, customs compliance. Standalone deliverable or credited toward full build.
• Sprint build: $4,999 fixed-fee, 6 weeks, ~200h @ $25/hr. Scope: Magento + Hyvä setup, configurable-product schema for shade × texture × origin × length, B2B salon portal, color-matching quiz front-end, basic subscription wiring. Custom scope for medical-wig + virtual try-on quoted separately.
• Hosting: $400, $1,500/mo on Cloudways / dedicated. Hair-ecom traffic is steadier than fashion-drop traffic, standard provisioning works.
• Ongoing retainer: $1,500, $5,000/mo for shade-range expansion, B2B portal iteration, medical-wig channel growth.

Credentials: I’m an Adobe Certified Magento + Hyvä developer with 7+ years of beauty + B2B + DTC ecom builds shipped across the EU, US, UK, and India. Multiple beauty-vertical (skincare, cosmetics, hair-care) builds where the SKU complexity (shade × texture × concern) mirrors hair extensions. Quoted in 24 hours, fixed-fee, $25/hr math visible on every line of the proposal.
