That will take some research. Do a Google Blog Search for some of the keywords in your industry and look through the blogs that come up. If you sell flooring then think about things related to flooring, perhaps house plans, real estate, and home remodeling for example. Look for blogs in these areas. If the blog has frequent posts and looks decent then check page rank.
Check around on the blog for the types of posts they have, read the about us page. Then if it seems like a good fit contact the blogger and see if they would be interested in a guest post from a flooring expert. You might even write a post beforehand and let them know the title of the post and that you'd be happy for them to preview it and then if they like it they can post it.
