Write some Articles Trial

I am looking for 2 x 1,000 word article about a VoIP topic that I will supply. They will be a comparison/review of two different VoIP companies. An example that I had someone write was magicJack vs. Net Talk, I will provide a sample of what I am expecting once I accept your offer. This is a test run and if your writing skills are good enough this could be a long term and ongoing relationship where I will want 5-7 articles per week on VoIP related topics for the next several years. The article must be 100% unique and able to pass Copyscape and also I expect to need to do very very minimal editing/correcting or needing to send back for revisions. My other writer generally puts an 1-2 images in with his posts and this would be much preferred to no images.
