Windows App to restrict and regulate access to camera and microphone

i need an application made that can control and restrict and regulate access by other applications on my computer to the camera and microphone, ie a privacy protection application. Please bid only if you are an experienced C# programmer. Do not apply if you are an India based software company, I don't have the time and patience to translate the above description into kindergartenish.. And please keep the bids in a reasonable range :)
