Copyright for App Company

We are looking for a person to write content for press kits. Our company will be launching 16 apps until the end of the year and besides that we will also require content to reinforce the company's brand. The copyright must reinforce company's brand, be commercially appealing and also optimized for SEO. I would like to have quote for each individual press kit content that includes: * App synopsis that will be displayed at the app store * Press release (related to the app synopsis) * Landing page text (related to the press release) * Blog post (related to the press release) * Social media posts (related to the press release)
