This is slightly off topic but might interest you. I have been working as a research scientist in Warsaw the past 6 years. I am from the UK and people, from time-to-time, ask me to do language corrections of their scientific papers and other documents. I am starting a website aimed at linking people who are native speakers with those who need their help, mainly for correction/editing/proof reading jobs.

If you are interested you can create your own profile on the site free and it will be available for users to see when looking for native speakers. Its also a jobs forum, so people can post jobs. The site is just starting, so now is a good time for new users, such as yourself, to get a profile up.

All the best,
