Weekly Blog Writing

We need a professional blog writer that has excellent knowledge on the latest internet trends.

The candidate will be required to carry out their own research into our target marketplace and write ongoing weekly articles, the quantity, keyword density and length of which to be determined again by their own research into what would be most beneficial in respect to SEO.

The candidate should also be familiar with Wordpress because we would like them to upload the content direct to our website.

Note: The blog section of our website (see link below) has been neglected for many years.

As you can see, the last posting was back in 2010!

We are firstly looking to establish costs so please provide the following information:

1. How many blog postings do you recommend uploading per week?
2. How many words per blog?
3. Cost per blog?

Thank you
Martin
