AO sized research poster into Power point Landscape size for online viewing

I have an AO size research poster that I need to convert into a Power point landscape size for online viewing. It is currently an AO size, and I need it to be converted into a Power point landscape size. I am not sure if I need the images in the poster to be edited for online viewing. I am looking for someone who can do the conversion and make sure everything still looks good in the Power point presentation.
