It’s not an unreasonable price for an end user. You could probably get more if you find someone who is interested in building a brand with it. Sounds like you’ve already listed it on DAN and Afternic.
Thant’s a good start. It’s a decent two word .net, but I don’t think it’s really something a domain investor would pay much for. You could try some outbound marketing. Perhaps someone has a domain something like findairlinejobs.net, who would be interested in upgrading to a shorter domain.
