Need help formatting your book into MOBI/PRC, EPUB, PDF, HTML, and/or a DOC (like for Smashwords)? I can help with that and I’m familiar with the specifications for various resellers. I’ll provide you with clean files with no weird characters that are accepted by various retailers in the formats you need. The variation in price comes from what state the file is in when it reaches me–if it requires extensive formatting to get things uniform (like if there’s variation in chapter headings or inconsistent spacing), that bumps it to the higher end. This also assumes your book is an average length. Excessively long novels–120K words and up–may increase the cost. Turn around time is a few days to a week or so, depending on my workload.
