Feeling sorry for you and hope things will get easier on the financial side. My advice would be first find any job which pays you, so that you can cover your family expenses. 1 month for a SaaS is toooo little time.

My first SaaS took actually 28 months before i get a first subscription of 18 USD/month. You need to keep working on the SaaS on the side. Do not stop it if you believe it is geniuenly good and there is market for it. Build SEO, GEO profile, do outreach like send 10 emails everyday post content on relevent communities and in around 6-8 months once you have planted enough seeds you will start to see a steady flow of traffic and eventual conversion, but this is too much you need to know, seo, geo, growth hacking, outreach, content etc, see what sticks and then narrow on that.

I was listening to this https://www.pmf.show/blog/solidroad-product-market-fit-cold-... maybe worth a listen. But bro I really wish you good luck, do not loose hope, find some work, keep working on your side projects. I am also an immigrant from a third world country to Denmark and I know, life is hell if you are not able to afford finances for your family. Best of Luck!
