Project Description:
I am currently building a website for clients thats wish to build a DIY calculator and shopping cart pages.

I need to create and instant quote calculator on the products page once the user enters their information.
It is for a fencing and walling shopping cart and is based on each section:
For instance the first section may cost $600 for 2.4 mtr section then the next sections may cost $350 for each following section or part there of.

EG if a front is: 9.6 metres, the calclator would be required to calculate:
Section 1 ($600) + section 2( $350) + section 3 ($350) + section 4 ($350) = $1650

Hoever this would change is customer has for instance a gate in the middle of the fence: (As first section will be applied twice)
see digram for example: therefore the equation would need to be:

Section 1 ($600) + section 2( $350) then gap for gate section 3 ($600) + section 4 ($350) = $1900.

Then a new equation needs to be created for two sizes thickness along with two sizes heights.
the thickness will be 75mm or 150mm.
the heights will be 1800 or 2100. all of these we have prices worked out for.
We have put together a basic one page type (demo) to enter measurements in, from their we want the calulator to basically tell us how many section a and how many section b we need to send to the customer, add the cost of transport (we can provide a table of cost to transport to various suburbs via postcode/ zip code), then take them to a payment gateway. Complete the transaction.

Complete transaction and send us an email with product to be sent, address (location) and so on:

We have issues with freelancers previously stating that they do the job obly to find out they do not have the skill sets, therefore we would be only willing to pay 25% intial payment, to protect ourselves.

This is a high priority job, therefore most likely will this project will be awarded within 24 hour period.
Winning applicant must have access to skype the winning applicant must speak fluent english.
