How long will it take you to finish the job?
Hello,
for proofreading 250 words, I would not require more than half an hour, depending of course on what kind of text.
Proposal:
Hello,
I am a native Norwegian living in the UK.
I can help you out with the Norwegian part. For pure proofreading, I guess 0,02 per word would be fine, if the work requires translation, a rate of 0,05 per word is required.
Please check my feedback, I provide quality work.
Many thanks
