The other day breeziness.com sold for $180 - its also a one word .com domain name, but they are horrible words which aren't marketable nor memorable.
Sticking pages on a site always increases its value, I'm not sure what the purpose behind the pages is however. Do you own the images you used?
I would critically say you could get $450 from the right buyer, but personally I wouldn't pay more than $200 (infact, I wouldn't bid on it because I couldn't use it, but thats where I would value it) - the page doesn't help until it starts to draw in traffic, and I think you need to do some more work before that happens.
