I have read your description and I am confident that I can provide you, your sister, and your friends what you need. An example of my editing prowess will be your content.
Please note that this is a manual edit as I have no access to computer at the time of editing, so all credits is mine.
Hello! I have taken the time out to write a short blog post that contains all the logistics of starting a business. All I need at the moment is someone to copy and edit this work. The individual should be able to add a bit of spice into it to make it sound more professional. This is a check list I wrote for my sister and a few friends who intend to create a startup. It is my goal for this blog to become more presentable for a broader audience.
I will stop here. I believe that so far, you have gotten an idea of what I can do when I proofread and edit it through a PC (the method most people use for editing). I will drop the edited content today if you award the bid to me now. However, whenever you decide, I promise to be through with the work, earliest, one hour, latest, two.
