I always take care of my friends and be with them when they are not feeling happy. I had some experience from mental health issues that I want to share to someone and chat to people
1. Try to interact with them first, for example, making videos and post online to see is your target audience feel related
2. If you have enough capital, trying to put Ads on different platform, I recommend pay per click Ads.
3. Make your service for free or giving discount to them, which allows them to try your service first to guarantee your quality
Feel free to ask more question :) Hope my advice can help your business!!
