Most of these projects are waaaaaaay to slow to reach profitability. You want product market fit ASAP. I also don't think it should be a programming project. Code is a tool, like anything else, and if you have no experience, it's tough to compete with experienced toolmakers. Instead, leverage some domain specific knowledge to be competitive. Does your country have a robust eBay market? I've found plenty of "beer money" success selling specific things there. If you know more about something than almost anyone else, you can monetize that via eBay easily and with excellent reach. For example, there's plenty of sellers in Russia/Eastern Europe selling vintage soviet machining/radiation equipment. In SE Asia, a million mom and pop shops moving ICs. In Japan, high quality tooling. Plenty of people all over just hawking the results of a university auction. I even buy from a guy in the US who only sells refractory ceramics. You can find incredible niche stores on eBay who are doing very well. Where the coding comes in is automating everything. For example, code to automatically print labels for my packages. A local database to manage quantities. A (rudimentary!) pricing algorithm to maximize volume or profit; the possibilities are endless. These projects are easy to justify, and the immediate improvement is clear.
