I am not sure what you require assistance with, but my experience is vast, both in clients and subject matter. The only thing I will not write is porn. I have a dozen books published for Kindle on Amazon, and have worked as a news reporter, ghostwriter and more.
My bid for $100 would cover up to five hours of research and writing combined. I have a reputation for being an excellent researcher, and I produce my work timely. I have never missed a deadline, and usually turn in my assignments well ahead of time. This ensures any corrections, additions or subtraction can happen before your deadline looms. I will correct my mistakes, without charge, should the article not meet your expectations. I do ask for clear directions, however.
