in this case you can easily sell your own product for 100% profits...
You said you'd be ok with $500-1000 per month, this means that if you have a product that sells for $9.99 (pretty easy sell for someone as experienced as you are in your niche) at a conversion rate of... let's say 2% (if you create high converting landing pages and know how to sell you can easily get 5% conversion or higher)... this means that you make 1 sale for every 50 visitors, which means $10 for every 50 visitors, which means you need to reach 5000 visitors a month to make $1000 a month in selling your product.
To get 5000 visitors a month is not hard if you put in the work and target the right keywords and - particularly important - if google doesn't fuck up your site out of sheer fun like they do lately. Or you could focus on other sources of traffic like reddit / quora / pinterest (although these might be time consuming), or you could go for paid ads (quite a few options around the forum for 300 Euros threshold GAds accounts if you take the time to search for them, I've just used one of these last week and it worked, you pay $80-100 and you get 300 Euros / USD worth of spending and if you do this repeatedly... well, you're bound to turn a profit eventually.)
well, that's for you to figure out, I can't help you with this one
true, businesses need to make money...
Regarding profitability, again, if you sell your own product (an ecourse, or even a simple PDF marketed as an ebook) you can easily put a 20-30 page PDF together on valuable stuff in your niche that you know people pay $100s for somewhere else, hire someone off Fiverr or other freelancing sites to create a nice ebook cover (or some marketing assets for promoting on social media / in paid ads networks) for like $50-100 (you might pay even less than $50 if you search well enough) and then upload the PDF to your server and link to it from the sidebar and from other places on your site that it makes sense (at the bottom of articles, for example)
