Hi Milfredo -
1) I would try the Gamblers' Book Store in Las Vegas: 702/382-7555 or
http://www.gamblersbook.com.
2) I purchased a program from Gamblers' Book Store in 1997 for basketball for $50. It made me realize how little I knew about the game, and I didn't buy the 1998 version. But, it seemed like a good program (it made me think), and the company is still in business 4 years later (an eternity in the Computer Business.) They post weekly updates to their database, so you don't need to do a lot of data entry. The Company's name is MicroBrothers Software:

Good Luck!
