I'm in need of 20-50 unique articles about "vitamin a for acne". They all must be unique and pass copyscape.
Each article must be at minimum 400 words. I prefer 800 word articles +, if they are 800 words, count them as 2 article, if 1200 words, 3 articles and so on.
Give me your best offer and how many articles you can write for that offer.
