Booking System / E-Commerce

Hi everybody,

I need a plugin, and I have been looking everywhere for an answer to this, but maybe I’m not using the correct terms…

What I am looking for:

Step 1: Choose School, Select number of children, Price (1 term, 2 terms, full year etc), Input parents details.

Step 2: Input childs info (number of children depends on amount selected in previous step)

Step 3: Booking Confirmation
Childs Name – School – Product Selected – Price

Step 4: PayPal.

If anybody could help, that would be brilliant. As far as I know, I have no budget, so free would be brilliant.
