I just edited the post with "INR" bro, not to create any confusions.
I assume you are either studying or working at the moment right? I hope it's the former most probably. Don't worry, you can allocate 6-8 hours per day for this. These are my suggestions:
1. Domain Flipping: What you have to do is, research thoroughly, and register catchy domain names, probably related to "Sports," "Fashion," etc. The areas where finding a good domain name will be difficult. You can just register a .com domain name for $1 (more or less), and you can sell them for at least 10x or 20x your investment. You can also do this with Expired Domains having good DA.
2. Content Writing: You said you can type 70 words per minute, that's really good, but it won't be much use here. But since you told me you are good at English, maybe we can do Content Writing along with your basic SEO experience. Instead of pitching yourself as a guest author, I want you to write something exclusive and detailed beforehand, then sell it.
Take this topic for example:
"How to disable or move away from Google AMP Completely?"
This is one of the most frequently asked questions out there, so what you can do is, you can write a detailed tutorial about this and pitch it to Bloggers (even to me). Along with that, you can promise (pinky promise) that when you write guest articles on other blogs, you'll link this guest article (written on my blog), thus generating a few decent backlinks for free. Be professional and be true.
3. Affiliate Marketing: There are so many platforms & products out there for this. Take this, you can help a Blogger.com or WordPress.com blogger to migrate, moving their content to WordPress.org, in return, you can request them to use your hosting affiliate link. You can also sign up on AppSumo, Amazon Associates, etc.
These are the easy ones I can think of bro, let me know your views, and I'll try to add more...
