Convert Newsletter to a Magazine format

Hello Everyone, I create a document called a Newsletter. Basically it contains stock market commentary, data and charts. The output looks okay at the moment. However I wish to make it look beautiful and professional. I wish to convert it to a magazine format so that the output looks as if you are reading a magazine/journal/book (something like what magster gives). I want you to give me a system that can enable me to create magazine output pdf. This should be compatible with different devices like phones, tablets and desktop. This means that if this pdf is opened in the above mentioned devices it should be readable/look fine. The main page can be a table of contents and then other pages can follow. Please advice how the content inside can be made better in terms of look and feel. A sample PDF that we use right now is attached. For details please feel free to ask me any questions.
