Quote style form for delivery costs - where do I start?

I need some advice before I start designing a form. I am a Photographer and I am selling my Limited Edition Fine Art prints through a Shopify website. The framed prints are of high-end gallery quality and it’s very difficult to have set delivery charges unless we have a postcode for the customer. So I need a quote style form for delivery of my prints before the customer decides to make a purchase so that they don’t get any nasty surprises at check out. Can anyone advise me, as to the best form template to start with? Many thanks and I look forward to hearing from you, Cath
