476576 Schedualing and POS

I own a horse farm that does public trail rides daily. What I need is a script that will make our schedualing very easy. PHP MYSQL and AJAX if possible. I have to have a spific list of fields for the adding 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 schedualing 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. and 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 google calandar 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. 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. I want the details feilds to be customizable. so I caould use the same script for another buisness. I would also like to be able to take credit cards from the software through paypal. but if there is a way to use a card reader that would be nice to have. I would like plenty of color and graphics as well. not just text and tables. Like I said if it looked like Google Calandar that would work great.
