SMS .NET based contest

Hi everybody, I need C#.NET console app coded that will process a contest based on SMS entries. Actually you don't have to worry about the SMS part, since all you'll be doing is reading and writing entries into a database. Essentially, the app will run on a loop reading new records from a database, depending on the content of the record, the app will either, add +1 to another table containing the senders phone numbers, return the current count or deactivate the sender's number. This result will be saved to another table. Also the app will have to keep track of which phone numbers have not sent a message in a configurable number of days and generate a notification for them (as an insert to a certain db table) as well as download a text file from an FTP site with numbers and sending them a message as well. That's pretty much it, you'll get some ready made classes to deal with some of this stuff already. Thanks!
