Website Script Project - User Inputs Data, Outputs a Graph

Hello hard-working freelancers. I am a Marketing Director at a Telemarketing company. We have an idea for an ROI calculator that we would like to host on our website. Here's how I envision it working: The visitor inputs data into form fields and clicks submit. Based on those inputs, once they click submit, a timeline is generated that is specific to the inputs they have entered. Make sense? I have intermediate website experience but this is outside of the realm of my capability. We have no preference on whether it is coded in Java, Flash, or any other platform, and we will count on you to recommend the best way to go. You will be expected to: - Code the ROI Calculator - Place it on a webpage template that I send you - Test functionality - Design it to be aesthetically pleasing IMPORTANT ELEMENTS TO THIS PROJECT: - Functionality - Design Once you bid, I will send you a sample of another ROI calculator which ours should be modeled on.
