I have 10+ year experience with MS Word, since I've been continuously working with it since elementary school. I've used it to write fiction, academic material, software documentation, seminars etc. I'm thoroughly familiar with its tools, including styles, header/footer, paragraph aligning and so on, as well as always being up-to-date with its newest version.
I may be a new freelancer, but it's in my best interest to gain good feedback and leave a client satisfied - the 3-day window specified in my bid is maximum time needed to complete the given project, and if you're not happy during the early stages with my work, I'll gladly cancel the milestone.
For any further questions, feel free to contact me. Thanks
