Blog content writing

I own [login to view URL] I am loooking for a permanent content writer that can write two unique small articles per week. My website sells wheels and tires so the articles will be in this niche. I will give the author a new topic to write about each week and he/she will write it and will also control the domain as well. The blog is setup through wordpress so it is very easy to edit. I will also need the author to be in charge of the comments on the blog as there are a lot of marketing spammers that use automated editing. The bidding is for one month of work, which i will pay up front and then we can discuss if we will continue from there.
