I'll develop a calculator for illuminated sign box costs

I design and build cost calculators for illuminated sign boxes — those very light-box signs that advertising and production companies install on the facades of shops, malls, and offices. Instead of a regular contact form, the website visitor selects the box size, lighting type (LED modules or neon effect), housing material — composite, acrylic, polycarbonate, or galvanized steel — and immediately sees the price and actual manufacturing time, without calling a manager.

I build the calculation logic the way sign production companies actually calculate costs: price grows from the lit surface area, a double-sided box adds material and labor, LED lighting is counted by number of modules and power supply capacity, and neon — by running meter. Rush manufacturing shows as a separate markup openly, not a hidden line in the total. You can add choice of mounting method, single or double-sided execution, printed or routed letters.

As a result, you get a tool that filters out random inquiries and saves estimators' time:
— step-by-step selection of size, lighting, and material with real-time pricing
— transparent breakdown: base price, lighting markup, rush markup
— responsive design for mobile devices in your website style
— editable tariff table — you change prices yourself, without a programmer
