Prices will vary depending on:
Type of work required – proofreading, editing, total revision of text
Complexity of the content
Writer’s general level of English usage and clarity of presentation
Time allowed for the work (short-term deadlines cost more)

Send me your complete text. I can then give you an estimate of the cost, without obligation.

The price for the work as a whole can also be determined per hour, number of words, or for the complete text by mutual agreement, after I have seen the entire text.
Partial payment must be made in advance.
Payment can be made by bank transfer (I will provide my account details).
