329006 Schedual

I own a horse farm that does public trail rides daily. What I need is a script that will only be used internally here on the farm. PHP MYSQL and AJAX if possible or a windows based software (would have to be networked.) I have to have a spific list of fields for the adding like the number of riders which is limited so it would have to be like radio buttons. Number of riders under 13, phones, names, And a notes section. I would like if possible to have a new schedual dispatch an E-mail to the customer confirming and all that stuff and also have an option to pay in advance with paypal. Which would need to be able to reflect on our calandar automatically. for the whole schedualing process a month view going into a week/day view. with our set list of times (that can be changed individually if you have the permissions.) Then for out in the barn I want to have a real simple display that lets the staff only see "today" stuff. Maybe a skype plugin so we call call from right there. That view though should be fairly large format so It can be glanced at and not have to be scrolled on a ~1200X~800 display. I want it to show the total price and have a link (maybe an F key) that will print a form for every rider. I want this to be simular to like office (if a windows app) or google calandar (if a script) Very GUI and large(ish) print so its easy and quick. We have to use this while talking on the phone so that makes is harder with there. Big buttons too (at least for the "today/list" view for the barn) I may use a touch screen out there but if not it will be a track pad that people with dirty hands have to use so still needs to be easy. And I want it to be customizable. Just the add apointment form so if I wanted to sell this program my customers could customise it to the info they needed.
