Help with my website

Hey im wanting to make an eCommerce site for my business. I will be selling made to measure products like, blinds and curtains. The problem is the pricing side of things. I would want something like this on my site /www.247curtains.co.uk/calista-ascot-gold-made-to-measure-curtains
so that the clients can enter their measurements, choose there heading and so on, then receive a price on how much it would cost. Does anyone have an ideas how i could achieve this through wordpress?
