Build a Auto Finance calculator for website

Hi there,

I am looking for someone who can build a Auto Finance calculator for one of the biggest car dealers in the UK.

You can find an example on this website:

http://www.hyundaiusa.com/financial-tools/payment-calculator.aspx

We don't need to have functions to match the cars with prices (like "Select Model, Select Trim level, and select powertrain")

But the rest of the calculation need to be the same as this.
For example, when the figures are typed in, the est. Monthly payment need to change accordingly.

On the same project, we also will need the budget calculator, which you can find on the same website:
http://www.hyundaiusa.com/financial-tools/budget-calculator.aspx

This would have the same function as the finance calculator.

We will need someone who can start immediately.

Please apply this job and if you have any questions on this project, just send me an email.

Thank you for your time.
