Startup Idea: Daily Fantasy Sports Backtesting Software

Startup idea to develop a software for daily fantasy sports players. The software will provide a feature for backtesting against historical sports data, which includes games, scores, stats, and more. The program would be designed in such a way that it will allow for user inputs, weighting adjustments plus an automatic download and update feature for the database. The software might run as a profitable monthly subscription service, given the lack of standalone, user-customized backtesting programs in the market.

I play dfs for profit. A bit of software for daily fantasy sports to backtest against historical data would be nice. Ideally it would contain a database of games, scores, stats etc. I could then adjust weighting to different factors to perfect a forecasting system. The program should be flexible enough to allow for user inputs. An auto one click feature to download and update the database daily would be brilliant. It could be a profitable monthly subscription service I think. There is not a standalone program that I can find. There are many sub services but not a user customized backtesting program.
