Need a Custom Kitchen Cabinetry Cost Calculator for a Furniture Factory Site

Our furniture factory manufactures fitted kitchens to order, and right now every price estimate is put together by hand: a manager checks the layout, the chosen facade material and countertop, adds the built-in appliances, and only then calls back with a number. This takes time and loses leads who want an instant figure. We need an interactive calculator on the site that walks a visitor through the same decisions and returns a price range and estimated production time before the call.

The tool should let a visitor set the cabinetry run length or pick a layout (straight, L-shaped, U-shaped, island), choose a facade material (enamel MDF, laminated chipboard, veneer, solid wood, acrylic), select a countertop type (laminate, quartz agglomerate, natural stone, butcher block), and add built-in appliances such as an oven, hob, hood, dishwasher and fridge, each with its own price adder. Pricing should combine a base rate per linear metre with material and appliance multipliers.

We need a specialist who can build this as a standalone page or embeddable widget, with prices and lead times editable later by a non-technical manager through a simple admin panel rather than hardcoded numbers.

Scope in brief:
— step-by-step form: length, materials, countertop, appliances
— live price and lead-time recalculation
— editable pricing table
— mobile-friendly layout
