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.
Choosing an industry also reshapes the catalog below to what applies to you — the full menu stays one tap away. Pricing never changes.
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.
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.
