I've offered to help a friend build his Van hire website. His company is small but you have to start somewhere right? He has 6 vans in total which causes an immediate problem. He doesn't want to take orders in case he can't supply a van.
Mission: To build an enquiry form which gives an accurate price quotation and takes customer information (except credit card information).
Problem: The daily rate of the van change depending on the length of the hire. For example, a 1 day hire would cost £50 per day, a 3 day hire would be £40 per day and after 7 days of hire the rate drops down to £30 per day.
Question: Is it possible to build such a form? If so, how so?
