Since I only work part-time, I cannot commit to more than 2 hours per day. For most editing/proofreading tasks, I have been able to comfortably deliver short-story collections and even novels within 2 weeks. However for fiction and content-writing, I can deliver about 3-5 articles per week and no more. I charge roughly $1 per 100 words for writing jobs and $1 per 500 words for editing jobs.
All other details are negotiable and can be worked out as we discuss the terms of the job.
