Review site advice needed

I have a really good domain name which includes "reviews" in it, the domain is aged , a PR5 with good authority.

My problem is monetizing it. I have had Clickbank product reviews and some other SEO tool reviews which makes me a few bucks here and there but I want to take this site to a new level.

What would you do? I have thought about business reviews. Seems like a lot of work for a saturated market. I thought about opening up the site to allow anyone to submit a review on anything, in article submission format. My worries on that is that it will just be another content farm casualty.

Does anyone here have any experience with review type sites? Any advice?

Thanks for the advice. This forum is super helpful.
