After Effects is one of the best. You can download a fully functional version from adobe for 30 days, or get a months worth subscription for 30 to 40 dollars. Of course there's a bit of a learning curve. Good Luck.
I've done tons of these types of videos using After Effects, it's really the best motion graphics package out there, but you really have to know how to use it well. Hipmunk's looks definitely like it was produced with After Effects.
If you would consider contracting the work out, my contact information is in my profile and I would love to show you my reel of previous work, that I did mostly in a former corporate video production job :)
