C# .NET Expert needed to update my video software

THE PROJECT NEEDS TO BE COMPLETED IN 1 WEEK. AND I NEED TO SEE A PLAN BY THIS SATURDAY AND SOME PROGRESS IN CODING BY MONDAY. my software is in C# on .NET. it does a lot but we need to add more features.. 1 - we need to save the videos as mp4 (the software currently records video to mpg) and make them sharable via twitter, facebook, instagram and email (this is all already possible with my software for photo capture). 1a. make the subject and text body updatable for emailing and each social media platform 2 - add a term and privacy page so people agree before they take part 3 - make it work with a gopro cam. right now, the software works with any webcam, so this might work already. 4 - save 2 copies of the video. 1 with a logo overlay and 1 without. the one with the overlay is the one we share on social media. 5 - add an audio recording option for people who don't want to show their face. there are some other things that need to be updated but all the main stuff is covered in 1 - 5.
