Content Writing

Hello, I am looking to improve my ranking in search engines for my website and for this i need to have someone to make original texts (no copy/paste) related to car rental services. My website is related to car rentals. Text should have 300-500 words, 1 x H1 header with the exact keyword and 2 x H2 headers including the keyword, 1 or 2 bold keywords in the text and general words that we can link to other pages (e.g. categories). Keyword must occur between 2.5% and 4% of the whole text. Maybe you have other ideas, so let us know. I am willing to pay 1$ per article. I will have a lot of work in future.
