Sorry but I am trying to find help for this forum and my business is so busy right now I can't do appraisals for everyone. So here is a free do-it- yourself tool and what I typically use.
go to http://www.networksolutions.com. Do a search on the domain in question. When the result comes up as taken, click on the link "make a certified offer", then on the right under the "enter offer box" you will see another box which says "select an answer" Select NO and it will give you a value as to it's worth in regards to traffic etc. Whether or not you'd get this amount for your domain is unknown.
