Content writer - repost

Hello, I need 20 very unique texts at a length of about 500 words each for our website. (If I find the right writer, this will be a weekly assignment of 20 per week.) The texts will be about fundraising for parks. Articles will be : • Must pass copyscape • Keyword density ~ 1-2% • Unique • English grammar must be excellent, with no grammatical errors. • Must have knowledge about SEO writing. • Articles must have bullet list, h1, h2, h3 tags and start with keywords. • Pictures with keyword and description relevant to article. Alt tag set to keyword. • Title must start with keyword. I will a brief text for each to use as a starting point. Each text will require some brief research. This will be a trial, if we work well together the job will continue. Thank you!
