What's the best way to sell it?

I built, and own, the website www.officequotes.net. It's got every word ever said on The Office. It's a great resource for anyone trying to look up a quote from the show. As you can tell from the site, I'm not a professional web developer. I knew just enough to get by, and had a lot of help from awesome Office fans.

Except for a short stint when I let someone else run the site, I've never put ads on it. It was my baby, and I didn't build it to make money, so I kept it clean and simple.

Now the office is as popular as ever (on Netflix and syndication), and I don't have time to do anything with the site. I could really use some extra cash from selling it.

Looking it up on some of the "How much is your website worth?" sites, ranges anywhere from like 5k to 30k. I know those aren't reliable, and in reality I'd get whatever someone's willing to pay.

So how do I find that out? Where do I start when looking for a buyer? Any advice? Help!
