Weigh the cost of a scoped history review against the cost of answering a request badly. Ask for a written quote covering document retrieval, drafting and certified translation, with hourly rates and exclusions named. These professional costs sit alongside the US$15,000 processing fee, which is described as non-refundable whatever the outcome.
What to pin down in the engagement terms
Get the scope in writing: which years are reviewed, how many documents are retrieved, whether translation is billed separately, and what happens if a second request arrives. Confirm who signs what, using the actual form-signature requirements as well as the engagement terms. And remember the US$1,000,000 gift is a later, separate stage, sent only when you are instructed to send it.
Review the existing agreement and any real release or refund before relying on the money again. The processing fee is nonrefundable and is charged per person. Build two budgets until the arrangement is chosen: the individual path and the separate corporate-sponsorship terms. Review the actual current instructions and any other applicable charges.
Before transferring, establish in writing whether any part is refundable and on what conditions, and record the source of that answer.
