The reason I'm the best fit for all of your freelancing needs is because I'm a native English speaker with an education and vocational background in journalism. That means that I do quality work, pay adroit attention to detail, and pride myself on my adherence to deadlines. If you're interested, go ahead and hit me up in chat and we'll talk.
My turnaround for a 500 word article, if research is involved, is about 2 hours. I won't be accepting 4 or 5 from you a day, but I'll easily do one or two. I don't mind doing this periodically, but I do need to find bigger fish. My hours are 9 a.m. to 5 p.m. PST - Monday through Friday - but I don't mind periodically doing a little overtime. I have a client I'm going to break this rule for this weekend because I like his projects.
If the subject matter is something that interests me, then I'll likely be available to do more work.
