I think you should contact @stellabelle for that. She has a much bigger audience (over 1000 followers), and has the SecretWriter thing.
I believe you're offering a commission of 0.008 BTC ($5). I've blogged for pay before and I prefer Steemit's Casino style because of the possibility of big payouts, the fact that there are no word limits, the fact that I have full creative control and can write whatever I want. Steemit is the most fun blogging platform on the Internet in particular because it's not feeling like a job, but it's like play.
We can negotiate on writing for your blog but I don't want to mix "blogging for pay" with "blogging for fun" and Steemit currently is in the "blogging for fun" category. It just happens to at times pay out well but I also realize that these payouts may be temporary because the price of Steem could go down below a point to where it will not be profitable or sustainable to think of it as a "blogging for pay" platform and this is why I always say it's more important Steemit stay fun.
