Definitely a strong domain but the niche is saturated.
When you have a premium domain, its perceived value is paradoxically diminished when the development does not do justice to the caliber of the domain. There is a reason why so many premium domains are left parked and undeveloped.
Perhaps the domain could be performing better by being more focused, that actually could mean selling just one product range either as a producer or as an affiliate. Not saying information is worthless but I don't see what makes your site unique vs the countless competitors. The domain is powerful and gives you more credibility but that's it. I haven't bookmarked your site, as I didn't see a compelling reason to do so. I am one more bouncing visitor.
I am not saying this is easy. Perhaps you picked the wrong industry. There are plenty of domains that are of lower quality but easier to monetize.
We all agree there is more value in the domain than the development that goes with it. This is the bad news.
I have to echo the comments above, I can't understand how you spent so much money to end up with a site that is quite average to be honest, and cannot be considered authoritative.
3K visitors, SEO, is all good but what ultimately matters is conversion and revenue. Bot traffic and bouncing visitors are not valuable, they just drain your bandwidth.
Since you didn't mention about revenue I am assuming it's low or at least not in line with your monetary investment. Or perhaps you prefer to disclose the figures to potential buyers only.
We don't have all the facts but in my view your current price expectations are too high. The actual value of the domain + site is not always 'at least what you invested'. You did admit you made unnecessary expenses (effectively wasted money).
The name belongs in the five figure range imo, but more is not impossible.
I would suggest that you contact a broker, advertise the fact that the domain on sale, start taking offers and possibly drive end users into a bidding war.
Good luck
