Generally, my rates for subject indexes for trade books run between $3.00 and $4.00 per indexable page. Textbooks and scholarly works may run higher, depending on the complexity of the text. Separate author indexes may increase the cost by $.50 to $1.00 per page. However, I am always open to negotiations and will welcome the opportunity to discuss your project with you.
I will be glad to provide a quote based on the number of pages to be indexed and a sample or description of the text.
