How do I get beta users for my side project with a 100% Free discount code?

Please suggest me some ways to get initial beta-users.

I have already uploaded to BetaList & ProductHunt: https://www.producthunt.com/posts/saleztalk

Also, would you mind signing up for my website to give me genuine feedback? Or can you recommend someone to use my product.

If you use "INDIEHACKERS" discount code, you'll get 100% discount. Valid for first 30 users.
