Conversion of Novel to ePub Format for Kindle using Vellum

Before I post this to Upwork, is there anyone here in this community who does the conversion to ePub using Vellum?

It’s a 96,000 work historical fiction novel. 5 parts, 90 chapters. List of characters. Footnotes.

This is not (yet) for publication - rather this is for epub distribution to select advance readers. (And yes, there’s a reason I need it in ePub and not just distributing as a PDF file - they need to be able to read it on their Kindle devices/app.)
