5k-8k are prices for LLL.coms with letters like X,Y,Z in them.. Not EJB.. You should be looking at minimum 10k+ from domain investors and as the above poster said, the sky is the limit with end users..
If you don't know jack about domains then get a good broker to handle this for you. Or search for which acronyms EJB stands for and contact those companies.. Very good domain and good luck with the sale!
