US Phone Number Creation & Verification Software

This program has two major functions. Firstly I have a database of all area codes in the US. Examples: 909, 951, 310, 213, etc, etc Then I have a list of all the prefixes associated with each area code: 909: 200,201,202,203,204,etc,etc. The software will create a list of all possible phone numbers by combining the area code & prefix & [All Numbers From 0000 Through 9999] Output: 9092000000 9092000001 9092000002 etc etc Now, as these numbers are being created, the software will use a special site (that I will reveal to the winning bidder or potential winners.) And using a thread based system (10 - 20 threads) enter the phone number into the site an read the sites output. Depending on the output of the site, the phone number will be placed in a CSV database for future use. For an experienced software designer this is a simple project and can be done in 1 day and 2 days max. Budget: $100
