Corporate video animation/recreation

Two corporate animated videos that we have inherited, which exist as a video currently but needs some minor editing and visual changes to showcase a different product. This means new images will need to be overlayed, new letters added over the top etc. We have some of the original image files, but not much of the original video material so some bits may need to be recreated using stock images etc. However, it's not a complex video/animation and a full brief will be given to make the job as simple and efficient as possible. More opportunities could be forthcoming on the back of this if the price and quality is good! :)
