}🟡start_booking(name, email, phone, location, service_type, ...)
Start a lie detector test booking for a person. Records the enquiry and returns a reference plus a ready-to-complete booking link with the office pre-filled. IMPORTANT: the person must finish on the website themselves — choose a time, accept the terms, sign the agreement, pay the non-refundable deposit (fully refunded if we cannot book you), and complete a short pre-examination assessment. An agent cannot sign or pay on their behalf. Do not put the person's contact details in any URL.
