Choose deliverables. See the whole engagement.

Every line below is a fixed fee for a defined deliverable, authored or reviewed under Dr. Thomas A. Hatzilabrou, M.D. — product-neutral and evidence-grounded by default. Every fee is published against its sourced fair-market basis: tap "Rate basis" on any line.

The catalog

Every deliverable. One fee each.

Quantities adjust the engagement, not the rate. Gold numerals mark the sourced rate basis for each line — the sources are listed in full at the bottom of this page. With an industry selected above, the catalog narrows to what applies to you.

Rate basis

The sources behind the numbers.

Worldborne Medical bills per item: each deliverable carries one fixed fee, invoiced 50% on engagement to initiate and 50% on delivery. Fees reflect physician (M.D.) authorship and review. Where a published market range exists, Worldborne's fee is set at or below the floor of that range; where no published range exists, the basis shown is a build-up from sourced physician advisory rates, labeled as such.
