Presentation for a speech

I need to create presentation, theme is business. What soft is good for this purpose? Can you help me with some advice?

 

If you use Windows try classics PowerPoint. It’s a little bit old-fashioned but it’s suitable for business issues. I've been using it for my college thesis

 

I've used Prezi before to create presentations. You can use it for free if you have a college email address.

 

Don't go heavy on the slides. You'll put the audience to sleep.
