The fastest way is to use a service like fiverr.com or hirewriters.com These are the ones that Marcus recommends and I have used both of them to have some articles written. Fiverr is around $5 for 600 word artical and hirewriter is around $8. You can have a turn around in one day or several days.
If you don't want to spend the money, go to http://ezinearticles.com
and do a search that you want articles on.
hopes this help.
