Hi Oliverries
I understand what you're after and it won't be an issue to get it created in the timeframe and budget specified. It would be good if you were to provide a little more info with your project so that freelancers can see what skills are required. My understanding is that you're after a calculator where your website visitors can enter the required details and you'll produce a quote for them, but there are a few questions. After they've created a quote do you need to be able to store a copy so you can refer to it later, or is just a one-time creation for the client? If it needs to be stored then there will need to be further info on the backend language and database requirements. Is the calculation fairly simple or are there additional parameters on top of those listed?
Regards,
Daniel
