What changes the estimate
Wallet and device count, whether historical ceremonies must be reconstructed from incomplete notes, travel outside central Seoul, rush delivery inside ten business days, and bilingual (EN/KR) binder production. Deposits are typically 40% on engagement letter; the balance is due on delivery of final materials. Refund terms describe cancellation and work-already-started rules.
