articles rewriting/synonyms exploring

I need copywriter to compose list of synonyms/similar phrases for 2-3 words phrases from my articles (300-320 words each). I expect you to make list of 30 synonyms per article (1-2 synonyms per phrase). You will choose on your own what phrases from my articles you want to get synonyms for, I dont care for that part. Its pretty easy and simple job and doesnt require any particular skill except good knowledge of english and some time. Please bid for 30 articles, not for 1.
