I need full list of features of Pro Version

Hi,
Can you send me a detailed list of features of the pro Version of this plugin please (and its price). I have a customer that has 3 courts (2 indoor soccer and 1 tennis court). He wants an integration with a customer database so his customers can have an account, that way they wouldn’t have to enter their info each time they make a reservation. Question for you; in case your plugin doesn’t have that feature are you able to customize it based on my needs for an extra charge? Thanks in advance and I’m looking forward for your response.
Nelson
