Hi there, I understand that you need an experienced writer and proofreader. I have been writing and proofreading articles for magazines, drafting business presentations for companies as well as reviews for products for years and such jobs are my daily practices. Therefore, I understand the professional and engaging language needed for your presentation. I am very familiar with PowerPoint, in fact, I just completed a task which requires me to proofread and edit. I have viewed the file you attached, and I am confident that I am able to provide you with what you ask for. I am still new on this site and hence you can see that I do not have any ratings nor testimonials to show you. However, I can assure you that if you work with me, you will not be disappointed. You are welcome to refer my past magazine article publications in my profile listed under the 'Resume' & 'Portfolio' tabs. Sample: "In 2003, XXX was proudly appointed as one of the strategic partner of ExxonMobil for the Selangor state to supply industrial lubricant (IL) to industries. As distributors, XXX has successfully met stringent requirements associated with product quality and handling, personnel training as well as qualification and brand representation". I do hope you are able to present me with an opportunity to work with you. If you are keen, kindly contact me via freelancer.com so we can discuss further. Look forward to do business with you.
