Data extraction, Spider3

Hello I want to spider a bus trip site that does trips between cities of one country. I need to grab different datas from the site. One of them is the price for each trip between each city. There are 137 cities, which means 18632 trip prices to grab. I want to do multi search grabbing in order to fasten the process. I prefer to have a desktop application for windows XP. (if the spidering can get faster on other OS, let me know) The application must spider in anonymous way using proxies. I will provide website and other specifications in PM in order you send final bid. Please send me examples of your work.
