289592 Javascript Cost Estimator

Hi. I am looking for someone who can make script for estimating cost of transfer. 1. Select From/to airport 2. Select Suburb 3. No. of passanger 4. Show price (readable) But the prices are very different. Each suburb (about 50) has slightly different prices and you take more and more passengers you need to make changes. For example: Suburb1 - 1passager 40$ - 2passager 43$ - 3passager 56$ Suburb1 - 1passager 40$ - 2passager 48$ - 3passager 78$ Suburb1 - 1passager 40$ - 2passager 52$ - 3passager 87$
