Points 1 and 2 are great options. If you have the time, you can also host engineering-based events, talk about tech, etc. Good developers are hard to find for the fact that there's a high probability that they are in great demand. Everyone's clamouring for their attention. Also, for the applicants that you do get, are they fundamentally terrible at coding/problem-solving or do they just not know the tech stack you're using? If it's the latter, you might want to re-evaluate as good to great developers are capable of picking up languages easily. You just need to give them some room to ramp up.
