Need an online calculator for custom-tailored suit pricing

I run a small bespoke tailoring studio and want a web calculator that lets clients estimate a custom suit's price before booking a consultation. Right now every quote is worked out manually by phone or in chat, which wastes time on obvious cases and makes pricing feel inconsistent from one client to the next. Some visitors simply leave for a competitor who shows a rough price upfront.

The calculator should walk a visitor through the main cost drivers: fabric category, from budget wool blends to premium Italian cloth, suit style such as a two-piece or a three-piece with a vest, single or double breasted cut, number of fittings, and turnaround urgency. It also needs optional extras: mother-of-pearl or horn buttons, working cuff buttonholes, contrast lining, and monogram embroidery. As options change, the estimated price and an approximate delivery date should update instantly, ending with a short form to submit the configuration as a quote request with contact details.

I need this as a lightweight, mobile-friendly widget I can embed into my existing site, with a price table I can edit myself through a simple admin panel, without calling a developer every time fabric costs change.

Requirements:
— Step-by-step form: fabric, style, number of fittings, urgency
— Live price recalculation on every option change, no page reload
— Vest and premium button choices as separate paid add-ons
— Price table editable without touching code
— Mobile-responsive layout matching my site's look
— Quote form collecting name, contact and chosen configuration
— Estimated delivery date shown next to the calculated price
