Need a writer to write recurring blog posts for LN about a video game social platform

Num. of words: 500
Tone: Informal/Casual
Extra notes: I'm the CEO of a social video game platform that brings game developers and gamers together for the whole development pipeline. I'm looking for someone to ghost write a biweekly or monthly blog that would get posted to LinkedIn, Medium, and our own website.
I would supply the topics (myself and my marketing lead) but of course would welcome additional topic ideas over time.
I would expect each blog post to be ~500 words.
Example topics:
Gamer Interactions during Development:
- Allowing Players behind the curtain during development
- How soon to involve gamers in the dev process
- Is it crazy to let gamers help you design your game?
Marketing:
- How to get your game discovered
- Building a fan base before launch
- The Power of Social engagement
- Streaming as a tool for user acquistion
- Why unique in-game items draw a crowd
