You don't seem like the actionable type of person. Instead, partner up with something (BHW has a great JV section).
The easiest, most fool-proof way to get the money back is to just rank for a few long-tail in a decent niche and get direct-partnership deals instead of the common affiliate stuff.
What you need is:
1) Somebody that knows the basics of coding (and/or WordPress)
2) Content Writer
3) SEO guy - or hire somebody at an hourly basis from here
4) Sales person (reach out to companies for custom deals)
You can probably do 2 and 4 yourself, just with a bit of work. If you're lucky you'll find somebody that knows #1 and #3.
I'd estimate $2000 towards a domain, $2000 towards PBNs (from reliable sellers), $1000 for the actual site (design, hosting, cloudflare, mailchimp etc) and another $1k for various cost.
Go get to work, nobody is gonna spoonfeed you more than that
