Urgent WooCommerce Sign Builder

I need a fully-functional sign builder added to my WooCommerce store so customers ordering business signs can personalise them on-site and check out in one smooth flow. The builder must:

• Load my pre-supplied design templates
• Allow live custom text entry with instant on-canvas preview.
• Offer colour selection that updates both text and relevant sign elements in real time.
• Push the final artwork to the WooCommerce cart as the product image/attachment and carry the chosen options into the order meta.

Please write it as a self-contained plugin or a clean child-theme module—no hard-coding into core files. Modern front-end tools such as React, Fabric.js or vanilla JS Canvas are fine as long as it stays lightweight and mobile friendly.

I’m on a tight deadline, so share an estimated turnaround and any similar configurators you’ve built. Once delivered, I’ll test across desktop and mobile; if the functions above work flawlessly and the order data lands correctly in the dashboard, we’re done.
