Write several complaint letters to various businesses

I need several serious complaint letters to be written. I have drafted each letter and included the details of each complaint. I have written only a rough draft and you will need to remove any rude or ineffective remarks. This task will take several hours to write all of the parties a quick summary that will contain all of the important information. I need someone who is very effective at resolving disputes with a clear and effective style of writing. Experience is dispute resolution or legal secretarial work or knowledge of the law, would be helpful. It is important to receive an effective response from each party which leads to the resolution of the dispute or helps the lawyer.
