Buying Need Experienced SEO Blogger Who Write Excellent Topics & Maintain the blog

It will be an SEO and social media company blog so need a confident and experienced writer with sound industry experience, latest updates and someone with interesting writing style.

I'd prefer someone on a fixed monthly job of $250 where the responsibilities will be:

Write regular high value posts on blog
Think of catchy & value oriented topics
Update blog with latest news and updates as soon as it happens
Post them in the most presentable manner and optimized way
Add relevant images with optimization ( I will share the source)
Keep the blog optimized with relevant plugins and updates
Promote the posts in social media after publishing
Take minimal care and management of social media accounts (Google+ & Twitter specifically)
Engage with other industry blogs
Communicate with industry bloggers for guest contributions & get them live
Complete copyright to all the jobs done for us (you'd sign the contract)
Availability of 1 hour everyday to discuss anything if you have or we have

If you're someone who can do it, PM me with your industry experience, some of your latest SEO/social media posts, one of your social media profiles and your skype id.

If this assignment goes well, we have a web design blog to handle if you're comfortable at a later stage to handle both.

Thank you
