asking on a carpet cleaning forum what a domain is worth is very silly. it's like asking on a rug doctor forum how to properly clean carpets.
there are many services that will sell your site and perhaps worth a look. i tried for one recently which was similar to yours maybe worse and the owner wanted £10k for it. i wasn't going to pay that but there could be someone who would such as was the case when the owner of facebook went from having thefacebook.com to facebook.com and he paid a lot for it, but a couple years before it was almost worthless. you should be able to get a decent amount for it if you really want to sell it now. $60 is way too cheap imo, you may as well keep the site and keep passing on the work for a referral fee and very quickly get that any ways.
