Writing for company blogs and websites

I am the Director of a growing scaffolding company, an event structures company and an events services directory. I wont go into it but the overall company (master plan) objective will become clear once I choose to work with someone and have a conversation.
I have a few sites that have respective blogs that need regular updates and fresh content ideally on a weekly basis. Our website content could do with looking at also. Whoever we work with we hope will become part of the vision and could eventually independently manage the companies online presence with little input from the company. At the moment I have myself and a manager writing content, its O.K but we are no Shakespears and we are becoming to busy and great content opportunities are falling by the wayside. The pay will start at £15 an hour for a maximum of 6 per week, on going until either party decides to quit. We hope this opportunity will grow in sync with the companies subsequent success and be a part of something you can make a difference with.
You must have good spelling and punctuation, nice use of language and imaginative.
