Build a module

Let me explain what I want to do. I have a taxi reservation module, but I do not like the booking form so I would like to do another one. For this module I have a component where I list all my database (my clients, my drivers, my vehicles, my partners, my bills ...) And since the module I add a booking through a form. So here are the steps that I would like the forms. To know is that I want a multi-page forms here is the link module that I use: [login to view URL] First stage (page): Ask the traveler's name and phone number with the function of auto suggest if he still in my database. If not, creat a button to add a new Seconde stage (page): Select address like the module ([login to view URL]) But when we add a customer from the first steep his address appears here But we can add a new address from pick up and drop up or we can suggest from the database pre-select address Also add a empty note (to writting some comment like number of flight...) add all detail then the module like Adult seats, Suitcases, Child seats add Select Date and Time Third stage (page): Payment method with some check box Fourth stage (page): down menu with various prices Fifth stage (page): Select a driver from the list Sixth stage (page): Summary Seventh stage (page): Bill sending from my model
