3 Unique article on the polyurethane business/week

I do not expect to find many if any people at all that will have knowledge in this field as it is a very precise niche. Please do not bid unless you really know the industry, otherwise, you will be wasting both yours and my time. This writer has to be able to at least read over an article, have a pretty good understanding of the information and be able to write up a similar article. Most people researching the industry already have a pretty good understanding of what it is because it is such a precise niche to be searching for. The business you will be writing for is similar to [login to view URL], [login to view URL] and linex.com. The articles you will be writing will be similar to ones like this [login to view URL] I will want at least 3 articles per week with 500 words minimum per article. I prefer to pay each week for that week's work. So when bidding, you are bidding on the price for 3 articles. I will want to maintain this into the foreseeable future as long as you are providing good content. Thank you for your time!
