In my professional opinion Amir could probably ask and get $1M+ for this site by the end of the week. More if he was patient.
The SEO value of this site is insane. Google pretty much anything Amir has reviewed and ASR shows up near the top. All you need to do to make $$$ is add affiliate links to every review (which could even be done in an automated fashion) and you've got a tidy income. Each sale you generate from those links can be worth a few percent of retail.
Then, pop a few ads on each page... . Advertisers could pay $10+ CPM and so without even working out the details, it's worth $100k per month aide from affiliate links.
Then, if you want to get really greedy, you could start selling reviews probably for $10k each, maybe more. This is almost what third tier YouTube influencers charge, and a good ASR review is worth more to certain brands. This would kill the site pretty quickly, but you would make your money back and much more before Google figured out what was going on.
