Go on ebay or amazon and try to find a used copy of Photoshop Elements.

You can also go to Adobe website and download 30 day trial of latest PS Elements 14. Any of them will do all you need. If you think you're going to stick with photography, you might as well begin learning PS sooner rather than later. Any more, about half of the technical side of photography is mastering software.
