INTERVERBA has fair prices.

For a non-specialised tranlsation of medium difficulty INTERVERBA charges 20-24 Euros plus tax per page (1500 characters, including spaces).
The pricing changes according to source language, type and length of text (the longer the text, the better the price).
The proof-reading and editing of scientific articles written in English costs about 50% of the above price, unless the manuscript needs thorough revision.
By fair pricing Interverba means: to acknowledge the experience and education required for delivering a high-quality translation.
