Create an Animation - Repost - open to bidding

We require an animation to be included in a language product as a prototype to get market feedback. The animation will be used as part of a role play where the student practices speaking sentences. The setting: A young lady walks up to a fast food outlet and has the following conversation with a male fast food worker. "Two cheesburgers and six chicken nuggets please." "For here or to go?" "To go thanks." "Do you want fries with that?" "Um, yes, large fries." "Anything to drink?" Animate as much as possible including body movements before and during the conversation, and mouth movements if possible. What level of mouth movement is possible? We have the exact timings for the sounds in all words in the sentences if they can be used For example, for "two" it is two sounds, with a "t" sound lasting about 60 millisceonds and "oo" lasting about 200 milliseconds etc Otherwise just simple mouth opening/closing would be OK. Give alternative prices for different levels of mouth animation if possible. We would like the output to be exported as a single video file for the whole 6 sentences as well as 6 individual videos for each sentence, so 7 videos in total, mp4 format. "Source code"/project to generate animations also desired. We suggest the animation to be done in Unity 3d, but other platforms are OK. Please say what the platform is to be used. Provide some sample animation video with your quote so we can get an idea of what the final product will be.
