Blogging and Article Writing

Looking for a regular professional blog or article writer for content for my website. All blogs and articles will be related to the products we have on offer and will cover many subjects. Looking for perhaps 2-3 per month to begin with of around 300-500 wprds, but happy to take advice on that. I am looking for key words to be used related to products and the topic being written about. I want to engage my audience and potential customers emotionally and get them feeling that we know what they are thinking, which encourages them to buy the products. Details will be given to the successful applicant, but for the purpose of selectioin, the products are probably the most advance technical base layer and sports underwear in the world. After extensive research and investment these products can provide a great amount of benefits to the wearer. My testers have only said extremely good things so far. Budget will be ongoing and applicants should submit price per blog/article and for how many words. Or consideration would be given to a monthly budget for an amount of blogs per month. Happy for the successful candidate to suggest topics for consideration for blogs/articles that will be on the website.
