[Typo3-dev] Development help needed creating function or extension

[wes currier]

I am in need of some development work. Below are the things I need.
This is over my head and I am not sure how to proceed.
If someone could tell me the best way to approach this I would be grateful.
If someone would like to do the work I would be willing to pay.

Start
Person enters a first name and zip code into a form.
They then select from a list of automobiles by maker.
This will return a list of models.
They choose one model.
Hit submit.
     Person is re-directed to personalized new page.
     Background corresponds to state they are from based on zip code entered.
     Their "name" replaces markers in the text file they are viewing.
     Audio file plays using their "name" that corresponds to a text file of the same content.
     (Audio will play from a flash movie that loads mp3's into a playlist while text scrolls on the screen.)

Script includes 2 functions.
  State
  Name

Possibly 2 additional functions
   Auto
   Type

State()	 {
     Takes zip code input
     Shortens to first 3 digits
     Loop through array for match
     Return = state ID
     Return = state HighWay
       Else
       Default ID
       Default HighWay
       }


Name() {
     Takes name input
     Loop male array
     Return gender = MALE
     Return = actual name
       Else
       Loop female array
       Return gender = FEMALE
       Return = actual name
         Else
         Return gender = MALE
         }


Secondary function[matches logic of state function]

auto() 	{
	Takes manufacture as input
	Return = option list of matching models
	}

type()	{
	model is selected
	Return = type
	}
(Type is used to set animation file in flash playlist)

Thanks for your time,
