Simple Video Editing / Effects

I have 56 video that vary in length from 40seconds to 6 minutes, I am looking for someone to add a company logo to the bottom right corner of each video (watermark) and also add a 3 second logo reveal to the start of each video. I can provide the logo reveal or if this can be provided aswell even better. I will then need the videos handed back to me ready to be uploaded to the internet (youtube).

Please provide a project price
