I have to say that is not easy at all to sell domain name at all.
Asking for appraisal of domain name you need to understand that there is no guarantee your domain name will be sold at the same high price.
That is the first stage and next day you will need to sell your domain name.
Selling your domain name you wll need to stick the idea to it.
Also you need have a marketing text explaining why this domain name is good.
I would say this domain name might worth low $XXX offers and that would be the best price for it.
