Dear DrugDeveloper,
I stumbled across your post whilst looking for new work. I am not an agency, but an individual trying to make a living in difficult economic times. I am a mother-tongue English speaker and have started my own business proof-reading scientific articles. My website is www.medsted.eu and if you are still interested then I think you will agree that my prices are significantly lower than agencies. In any case I am looking for the maximum publicity to promote my work, so if you are interested then please get in touch!
