Simple Writing and Presentations

I need someone with good English to help with the preparation of simple landing pages and powerpoint presentations. You will bascially be looking at sales pages and articles and creating bullet points to use on the landing pages and in the powerpoints. The focus will be on identifying the most important points and phrasing them in a "sales focussed" way. Initially I want 2 hours work done to assess suitability for the task. I am looking for someone i can use on an ongoing basis so please quote for the 2 hours work and I will assume that this rate will also be the long term hourly rate should I continue to use your services.
