Write Internet marketing blog posts

I would like 4 posts written for my internet markeing blog.
The posts I would like written are
1) getting traffic through social media
2) List building tactics
3) Top copywriting tips
4) top 7 twitter strategies

All posts should between 600 - 750 words
Only bid if you are willing to add your photo and author bio. I dont like taking
credit for others work. This is win - win, you write posts, you get the credit and receive exposure, I publish on my blog, visitors see I have high quality posts on my blog and come back.
There is chance of future jobs.
