I need an Animated into for my webseries

Design details: This is a 15 seconds intro to the Condensed Histories Web Series. A medieval style sword falls against a sky background. It passes by pyramids floating in the air. It passes through the centre of stonehenge likewise floating. It passed by a Roman Helmet, then a castle, then a smoking C18th factory, then an aeroplane which flies past, and finally lands in a 'stone' on the front of which is written 'Greg Chapman's Condensed Histories'.



Any questions, let me know. Please note the budget above is based on an offer I have already have, please do not bid well above this budget.
Ideas for the visual style: In my mind I envision 3d CG animation, but am open to suggestions from 2D animators and other styles as well. I do not want a videoscribe/whiteboard style animation.
Extra notes:
