Add Screen Share (using open source) to our existing Live Video Conferencing Web App

Our program is written in angular. The framework is .net. The screen share feature we would like to add to our program is available in many different open-source programs and can be integrated into our live video conferencing program. If you have experience in this type of project and are an expert in angular and can complete this feature fast, please send your experience info for consideration. We’ll pay you after the feature is completed and tested. In addition to the screen share feature, (once it is completed) we have several more we would like to add. Maximum we have budgeted is $300 for working and tested in our program and delivery within 4 days.
