A simple ''Tee Time'' system: Reservation Database

My business is a golf center that is open 365 days a year, we just bought 5 golf simulators that can simulate a full golf experience all year round. These simulators have shown a great impact on how our business will run. Due to the high volume of people we need to develop a "Tee Time" system so that people can phone in to reserve a slot and a time. I want this program to be very user friendly and have a very nice GUI. There should be an options menu to configure the program for our needs. For example, changing our hours of operation etc. etc. We want the program I would like you to contact me before bidding so you can clarify what you can offer my business and what makes you stand out from other developers. This is a very simple database/ time system to make; I know the one who wins will be very successful in making this product.
