Schedule Maker

Custom Scheduling software for non-profit organization, sports league. We require a flexible software scheduler that allows for manual manipulation. The software should have an automated and manual mode so that our scheduler can generate a schedule and then manually manipulate (preferably a drag and drop wysiwyg type interface) events that need it or manually create a schedule from scratch. The end-product would have a table-style calendar with hours of the day in 30 minute increments on the y-axis and the list of locations on an x-axis. We would want the ability to schedule up to approximately 150 teams per week. The software would store data that we could input on an annual basis. These are our organization specific terms: Discipline, the Age Division, the Tiers, and the Team Names. It would give us the option to generate a weekly game schedule for each Age Division and Tier, or allow us to manually create a schedule. The schedule should show up as games in 90 minute blocks. Manual adjustments should be easy to make - preferably by dragging and dropping the game block from one time to another. Once final, the schedule should be able to export to .csv or a specific format that can be utilized by our website / webmaster (.csv is easiest). We have tried out of the box software but it doesn't offer the flexibility that we require to move games manually and on short notice.
