Hi stella630,
don't go too far in search of a highly experienced academic writer.I am academic writer with years of experience writing reports, different types of university-level essays, powerpoint presentation, critiques and host of other top-notch presentations. I am well versed at MLA, APA, Chicago and Harvard citation and referencing styles.
In addition, I have written extensively on climate change due to changes in the concentration of carbon dioxide and burning of fossil fuels. These and so many other related topics have been written by me.
Please refer to PMB for samples.
