flash actionscript: hi all,

I have a project , which needs to be done entirely in Flash. It should have a
product comparison table.When we click on a image and drag and drop into the
comparison table, it should reveal all the product features.
I was wondering how much ActionScripting it needs. I am an intermediate flash
developer but a beginner in Action Scripting..
can any one tell me how to do this kind of stuff and also how long it requires
to finish it. I want to know if its too complicated, so that I can decide
whether or not I want to do this project.

Thank you for all your help.
