Primarily: experience, process, and deliverables. A $300 service typically assigns your project to an available generalist writer with no discovery process and minimal revisions. A $3,000 service usually provides a senior writer with subject-matter expertise, a structured editorial process, multiple revision rounds, and a polished, formatted final file. You're not just paying for words; you're paying for strategy, quality control, and a product that reflects your brand professionally.
Both can deliver excellent results, but they serve different needs. A freelancer is often more cost-effective and flexible for straightforward projects. A full-service agency like Berg Publishers provides editorial oversight, project management, formatting, and design under one roof, reducing the coordination burden on you. If your eBook is tied to your professional reputation or a business goal, the structured support of an agency is usually worth the premium.
For business and authority eBooks targeting a professional audience, 8,000–15,000 words is the standard range. This is long enough to deliver genuine value and position you as credible, but short enough that readers actually finish it. Lead magnets can be shorter (3,000–6,000 words). Full-length nonfiction books intended for retail typically run 25,000–50,000 words, which moves into a different pricing category entirely.
You should, but always confirm this in writing before signing. Reputable services transfer full copyright to you upon final payment. Some lower-cost platforms retain partial rights or license the content rather than transferring ownership. Always look for a "work for hire" clause in your contract that explicitly states you are the sole owner of the completed work.
For a 10,000–15,000 word eBook, expect 4–8 weeks from kickoff to final delivery with a quality service. This includes a discovery phase, outline approval, first draft, revision rounds, and formatting. Be cautious of services promising a finished eBook in under two weeks at that length; speed at that pace usually means a template-driven, low-research product that won't represent you well.
