That still won't help you. A tradename (e.g. DBA) is not an entity. It is simply another name that you use to conduct business. So a tradename cannot be a trustee. You'd be the trustee. And when using a tradename, you still sign things in your own name, for example: John Doe, D/B/A Doe's Lighting Products.If you could use a DBA, the DBA name would be on public records.
