I think it's a good domain, highly brandable.  Personally, I think it could be worth more to the right buyer.  Have you tried marketing to online recruitment agencies for example?  It's only worth more to a company that has a big recruitment business going.  
Remember however that an offer is an offer, so it depends on your personal circumstances as to whether you accept it.  
Sent you a PM as well.
