Just a quick note regarding the two programs I suggested above. They may look a little daunting at first, because they are both really powerful programs, packed with all the features you could ever need...
However, dont let that put you off, because you dont need to learn EVERY feature. Just how to do the stuff that you need to do, and chances are that because there are multiple ways to do whatever you need, and plenty of help online, its actually easier in the long run, than learning a rigid, yet simple program, that you could easily outgrow.
You really cant go wrong with either of them
