Also, related to the third point, try spending less time talking about what you want from an applicant and spend more time talking about what they want from you. In general this will attract more (and more good) applicants, but it's especially important in this case because, as you and others have said, your ideal applicant has many other options. They don't need to work for your company, so you have to make them want to. People are motivated by more than just money too. They want to work on interesting projects with interesting people. They want to grow professionally and expand their skill-set. They want to feel important and be recognized for their work. And they want lots of other things too. You need to speak to as many of those wants as you can.
