I find rewriting articles a lot harder than writing a researched article from scratch because you are working within someone else's syntax and that is difficult.
If you write quality articles then you shouldn't need to be writing for $3 an article - up your prices, respond to requests for articles via pm and provide links to work online and you should get at least two or three times that for starters.
Links to some of my work online time for writing each of these articles varied between 20 mins and an hour and a half. http://ezinearticles.com/?Places-to-Visit-by-Car-From-Nice&id=3727823 http://www.officefurnitureonline.co.uk/news/post/Its-an-Old-Spanish-Custom.aspx http://www.finweb.com/mortgage/do-you-need-a-solicitor-for-a-remortgage.html http://www.ehow.com/about_6664544_education-qualifications-teachers.html http://www.ehow.com/about_6677114_hr-training-development_.html
