This project is an engineering website project as it appears to need SignalR which indicates that project will highly engineering oriented. On top of that video streaming is already a very engineering intensive coding. I happened to be an engineer by training, at the same time I'm also knowledgeable and skillful in programming and web design, especially in Microsoft Technology and ASP.NET. With both expertise in me you should have no doubt about my ability to perform with your project, and I'm pretty sure that computer science graduates could not perform with this type of programming.
Due to the engineering nature and the weight of this project, I'm extending the budget and duration more than what you proposed since the value of the project is much more.
