Once this person has a financial template, they can use it to create forms the template will simply guide them through. The mere fact that the template has certain line items _ like the Balance Sheet, for example, forces you to think in a well_organized fashion and gather the information according to the structure of the template _ cash balances, accounts receivable, fixed assets, liabilities, etc. The same goes for a Business Plan. A well_designed financial template can steer you away from making some fundamental mistakes. A client of mine brought me a self_prepared Business Plan once and we both smiled at the many line items he had on his Profit & Loss statement which really belonged on a Balance Sheet. With a professionally designed template, he wouldn't have made that mistake.
Video _ Video is a great way to take people on a tour with photos, show the development progression of an idea, inspire, teach, announce something new, or otherwise show sequencing and motion. And video is SEO_friendly for websites. Create your slides with pictures, text, and whatever other graphic components you want to use to show your idea concept. Add narration and transitions to your slides, setting transition timing to work with your narration as appropriate. Then use the "Save and Send" option at the "File" menu tab and "Create a Video". You can add music as "narration" prior to this stage of the process, or queue music to the video with a video editor after you create the visual video. I've created many videos using PowerPoint without expensive video production software and equipment!
