Firstly you are talking about a system that already probably exists, so I'd narrow your focus to specifically what you want to do and then ask this forum again; but this time asking for recommendations as to tools on the market.

Then I would visit their websites, read the materials and download a few trial versions.  Play with or otherwise evaluate them.

Now; an important question to ask paralell to this is "What are the goals of the project?"  When answering this question shape the words around business capability.
