Tess, I work for the same company as D-A-L. Our software will do much more besides what you want but I think that it ought to do everything you need pretty comfortably as well without you having to worry about the other stuff that it can do off of different menus. It is based around a true Windows Explorer-style tree. You might need a customised report to be written to get the data out in exactly the format you want (although it does export to Excel if you don't mind tweaking it a bit afterwards).
In terms of cost, it quite a few hundreds

....... but that's extremely competitive for the kind of program that it is.
PM me or D-A-L and we can give you a link to the company web site so that you can view one of D-A-L's Flash demos if you're interested
