Translation German - English (Railway Industry)(2)

I'm looking for an experienced and reliable translator who can translate articles for a railway industry magazine over the period 30.05-13.06.2011 (the last translations should be delivered by midday on 13.05.). You will receive these texts not in one chunk but gradually and it is expected that you also continually send back the individual texts after translating each one. Some of the articles will be quite technical, so please only make an offer if you have a good grasp of railway vocabulary and plenty of experience translating from German into English. Total amount of text: 60 000 characters (including spaces). As the articles are still being written, it is difficult to state the total amount of text. It is possible that there will be slightly more (max. 15 000 characters), which you will not be expected to translate as part of this project, but please be prepared to make an additional offer later for the extra text. Please also state whether you are prepared to do a short trial translation (1226 characters). I look forward to hearing from you.
