Authority Article Needed

Looking for a high quality writer to write white paper type articles. Topic is Tax Lien Certificate Investing. I will give you a list of keywords that need to be included in the article. This needs to be very well researched and written as it will be used as an authority type document. I've hired hundreds of writers over the years and quickly recognize garbage content from well researched, well written material. Please only apply if you are capable and willing to put the effort required into this project. The document should be approx 2000 words in length. Needs to be an educational type article educating a reader on what Tax Lien Certificates are, how to buy them, the advantages of buying them, some potential pitfalls, etc. Our site sells a course teaching people this information as well. So please don't recommend any paid products. If you do recommend additional resources, please ensure they are governmental type resources. We eventually want to create about 20 of these types of high impact pieces, this job is to create one, once we find the right writer, we will continue on with completing the 20 pieces and will have plenty of additional work on top of that.
