Data Import Utility - RDB to MSSQL

We need a Windows server service with editable options to be able to go out on a predetermined time schedule to access a USGS website to grab data from a dynamically generated RDB file. The data will then be collected and based on a set of rules, with some sorting then save the data in a MS SQL 2008 server DB. We have setup a Database already where the fields will be populated in to the proper tables. Details of which can be provided to the coder selected. The website this data is being pulled from has a reference page at? <[login to view URL]>? ? and Example of the data can be found at? <[login to view URL]>? The data consists of a "Site" or Station with a date/time, a one to several parameters with a data value. We have between 15 - 20 stations that we need to collect data (Without duplicates), we need to be able to add, sites,? parameters? and adjust the mappings to the relevant tables and translate a site number to a station number that we use, basically some sort of mapping rules table we can edit and a way to adjust how often data is check and collected.
