Create an online calculator - for foam website

Our website GB Pit Foam is currently being optimised for search engines and we would like to update the current iFrame calculator with a more user friendly one. We would like to update this calculator: [login to view URL] The new calculator needs to calculate foam cubes, foam logs and base liner pads. In addition to that we would like it to work out delivery cost based on location from our factory. If it could be done in a step by step wizard it would be best. Our in house design team can create and liase with you directly for this. Please note, if the programmer selected does a great job at a competitive price we will have a lot more work for the future for our other websites. ---------------------------------------------------------------------------------------------- Calculating the Volume of Foam Cubes or Foam Logs Length x Width x Depth = Volume m3 200mm Cubes Length x Width x Depth = Volume m3 Volume m3 / 0.008 150mm Cubes Length x Width x Depth = Volume m3 Volume m3 / 0.0034 600mm x 100mm x 100mm Logs Length x Width x Depth = Volume m3 Volume m3 / 0.006 ---------------------------------------------------------------------------------------------- Calculating Foam Base Liner Sheets/Pads - 285mm thick (standard size) Length x Width - Volume m2 Length x Width / 4.76 = Number of Sheets/Pads (Multiple by Selling Price each for Sales Volume) We haven't done this before, but uses the same standard metrics for calculations, just used the Length and Width (we already know the depth) ---------------------------------------------------------------------------------------------- Delivery Charge Ideally we want to be able to calculate a delivery price:- The only way I can think of doing this is to ask them to enter a postcode, which then calculates mileage from our postcode here (HP12 4HG). ----------------------------------------------------------------------------------------------
