Charges are based on the word count and on the time required to complete the job. The fee will depend on the editing or indexing required and will take into account the nature of the particular text.
I will need to know how long the document is, and what service you require.
If your document is in Microsoft Word, I will use Word’s Track Changes to edit it. If the document is a PDF, I will use Adobe's Comment facility.
For indexing, I use Sky Index Professional, and submit the index as an RTF file.
