Kamath8 Resale Software Build

I need a brand-new software application branded “Kamath8” that I can package and resell under my own label. My focus is firmly on a technology solution—no interest in physical repairs or mechanical services—so please think in terms of a clean, well-structured program with solid, modern code.

Key things I’m looking for:
• Complete, production-ready build (desktop, web, or mobile—whichever framework you feel best suits the concept)
• Source code and documentation delivered with full resale rights
• Simple installer or deployment guide so my future customers can get up and running quickly
• A brief user manual or onboard help section in English (Sinhala localisation is a welcome bonus but not mandatory)

Acceptance criteria
1. I can install the app on a fresh machine and run it without additional paid dependencies.
2. The licence terms you provide clearly allow unlimited redistribution under my brand.
3. All critical bugs identified during hand-over are fixed promptly.

Tell me which tech stack you propose, how long you’ll need, and any past work that shows you can create polished, commercial-grade software. I’m ready to start as soon as I know we’re on the same page.
