data scapper script

Looking for a few data scrapper scripts @ $5/script Use any open source scapper and build the logics php/asp.net/desktop c# app any of it is ok. The script must be able to auto pause and start again as it needs to follow page levels and extract from many pages. The general logic is same for all the logics, extracting data in a patient child relationship. Should generate an auto increate number to link the relationships and dump in mysql tables. Give examples of scrapper you made for extracting data in treeview relationship. All the source codes must be transfered.
