Website Development From Provided Design

I run a web app for planning LED channel‑letter signs. The user types a word (or uploads a pdf/svg) and the app must automatically place LED modules inside the letter strokes so the acrylic face lights evenly — the same idea as bounceled.com and "LED Wizard" sign software...
