Sales/ Corporte Presentation via Powerpoint

I would like someone to help me with creating a powerpoint ( sales/ corporate presentation for a manufacturing company) but all information and pictures would be given. It needs to have a: a) very professional (outlook and writing) b) imagery, logo ( will be given / you can take via the internet if needed more) This presentation gives a 'big picture' story of what my company does. It is often used when meeting clients for the first time. Sometimes this is a separate section within a larger presentation. It contains background information not related to a specific decision. Theme colour has to be dark blue in line with company logo More pictures will be given when bid has won. Needs to be under powerpoint
