If the goal is statistic, get a free hosting and use Google Analytics.
If the goal is parking, list the domain on a parking company like Sedo, Bodis, PC.
If the goal is sale, list the domain on a marketplace like DAN with a BIN price.
If you want statistic from a parking company for a domain that you want to sell is too confused.
Visits can be completed unrelated to parking revenue and/or chance to sell the domain.
