Create a time allocated 70 hours package (eg)

I would like to be able to create a package that's built around time we have a 70 hour Doggie Day Care Package and I'd like to be able to let our customers book online and count the hours down automatically but I would like it to have an additional feature for we can allocate double hours for example if our customers come before opening hours which is normally 10 to 6 if they come at 9 am, we take double the hours. Then they can be sent an update of how many hours they have left per week and then prompting them to buy a new package when they get down to their final five hours this would be amazing. Also another feature would be if we can set up public holidays at double time as well.
