Create an Animation for new product demonstration

Hi there, We are looking for someone to make a 3d animation for a new product. The product is already 3d modelled and can be delivered in .stp or solidworks format. (photo attached) More details will be given to successful candidate. Script is about 4-5 slides long with various text displays and movements. Other models needed in video will be an ipad/tablet and a smartphone/iphone also some sort of industrial high voltage machine perhaps a welding machine or something similar? (can discuss) The script of the video is written and should be fairly simple to put together. No speech required although if you are a confident speaker perhaps we could add? There is nothing tricky such as water or dirt to be animated pretty much just products in stationary position and a screen showing the ipad app working. More details to successful candidate. Thanks
