I specialise in written translation (literary and non-literary texts) and audio-visual translation (subtitles, dubbing).
I price each text individually, but below you can find approximate cost of different types of services.

Rate per conditional page (1800 characters with spaces in target language)

Translation from English into Polish: 30–50 PLN
Translation from Polish into English: 35–60 PLN

Polish text
Proofreading: 5–15 PLN
Proofreading with editing: 15–30 PLN

English text
Proofreading: 10–25 PLN
Proofreading with editing: 20–40 PLN

The rate depends on the quality, complexity, technicality of the texts and the time of realization.
