The domain is a bit long, and it does not give anyone a significant business advantage. The "business opportunity" of creating a website about accounting techniques does not offer significant "easy" profit, the profit would be "difficult work". That said, the domain is suitable for creating such as website, it is a nice descriptive domain and I could see it selling at $200. If you are happy with that price, then great. However, you are likely to have to actively market this in order to make the sale.
