Hi!
I'm deeply interested in this project of yours. I don't know where to start. I´m a League of Legends player, currently unranked because I don't have that much time lately, but I normally end up in high gold, I´m proud to say I´m pretty good at the game but not that much too climb to anything more than gold. I play the game since 2014, I think, maybe even more before, in season 5 or 6. I still consume a lot of League content, mostly videos, I´m aware of the meta and all the new updates, like nerfs, buffs, events, new skins, and Esports.
For my writer side of this project, I have been writing content for web pages for 5 years now, I recently joined freelancer because a colleague told me about it, did some projects but didn't end up in anything so if we can talk I would gladly enter to this job with my full time, but as we grow we can work those things out. One thing I think is really important in this kind of job is communication, so I would like to talk to you about more details about the kind of content that you would like on your page.
Other than that I read all the requirements that you listed and I feel confident that I match them, normally I struggle in other jobs because I´m a little too casual and friendly in the way I write, but I think that for our readers that are more likely gamers this kind of tone is gonna work great.
Lastly, my pay per 100 words would be 0.80, like I said this job attracts so we can talk about my pay if this doesn't work out for you.
