Realtor Database

I need a database of realtors. Several recent projects have requested similar information, including: 127475, 81822 and 64302. I do not care how you get the data. Here is what I am interested in: 1. Realtor name 2. Phone 3. Fax 4. Email 5. Address, City, State I need the data in csv, xls or Access. I do not have a preference geographically. I'm interested in as much data as I can get for as little cost as possible. If you generated a database for a previous client, this may be a very simple project for you.
