Rates for indexing vary from project to project, depending on the complexity of the work in question. Generally I charge between $4.00 and $7.00 per indexable page depending on the density and complexity of the text in question. For specifics, please contact me with a sample chapter from the work you want indexed so I can look it over and discuss the job specifications with you in more detail.
Other things I will discuss with you at this time will include the time-frame/turn-around for the index, any length restrictions, formatting and other specific requirements for your index.
Contact me at email@example.com for more information. I’m looking forward to working with you.
