Open www.opapro.com (or /zh for Chinese), tap Get a free quote, and upload clear photos of the issue with your ZIP and a short description. In about 30 seconds you get a price range and suggested trade.
Pick a service option, verify your phone, and choose your preferred pro language if needed. Most jobs use a $1 card authorization (not a charge) until you sign off after completion; large contract jobs skip the $1 step.
Choose a visit window and submit. Your pro can message you in-app; track status under My orders. To cancel, contact support — card holds are released when the order is cancelled.
After the job, sign the invoice on-site, then pay the final amount. Opa Pro keeps messages, photos, and receipts in one place.
