Excellent Content writer needed urgently - Repost

I have around 50k words of content each month that needs to be written (12.5k per week) - and I am looking for a handful of writers who are interested in a long term engagement, are reliable and are comfortable using tools like Surfer SEO for optimisation (if you haven't used this before it's easy to learn).

Please respond to me with the following:

1. Rate your content quality on a scale of 1-10 (10 being the highest) - please be honest with this
2. Details on niches you have worked in
3. A few samples (preferably one product/conversion focused and one blog)
4. Your preferred TOV
5. Your hour availability
6. Will you be having any assistance on the content or will 100% be completed by you?

Cheers!
