Hello Sir/Madam,
I graduated from an online university in April with my Bachelor's in Business Administration with a Specialization in Accounting. During my prior professional and collegiate careers, I have completed numerous PowerPoint presentations. Regarding to the PowerPoint projects I completed in college, I always received perfect marks. Not only did I complete my Individual PowerPoint Projects, I also was the Group Leader for some Group PowerPoint Projects where I was responsible for taking several students' work, proofreading and editing it, and finally compiling all the work into the Final Project before submitting it to the other students for comments and to the instructors.
In other words, I have excellent skills with PowerPoint and would love to work with you on your project. I can start in the morning (as it is night-time here in Alaska, USA), if you would like. I look forward to chatting with you soon.
