I am American-Canadian and I write my own papers. I have extensive experience in writing academic papers and teaching that subject plus more at MBA level. I am semi-retired and need to augment my pension, so I do what I love and my papers generally get high marks.
Please check the portfolio. I have my resume and samples there. Files are self-extracting archives, so your antivirus may scream, but they are totally safe. You may have to turn the antivirus off for the download period. Too many people do not have or know how to use WinRAR, WinZIP or Stuffit, and these will unencrypt with a double-click. I do not put unencrypted files up in order to protect them from being crawled and published by search engines. Even though these are no longer confidential, as they are already published or turned into a plagiarism checker, they still should not be splashed all over the net, as search engines would do.
If you want a really good paper think about paying reasonably for what you need. Most of the cheap bidders and even some high bidders are third world jobbers with subcontracted second language writers. So be careful you check the feedback, not just the numbers. The numbers are misleading. It is also helpful to check the reputations of the feedback givers, since the jobbers artificially inflate their stats with multiple accounts.
