Looking for business ideas

• Available capital: 1000€

• Skills and experience: Web development (no-code, still learning to code but can build a website on my own). Certified as an IT technician, worked as an IT professional for about a year. Experience in automotive sales. Ads managing with Facebook ads Marketing

• Preferred industry: With just 1k, there’s not much to work with, but I’m interested in real estate, e-commerce, and marketing.

• Preference for online or brick and mortar: Online preference.

• Have you run a business? I’ve made around 200€/month with a print-on-demand store, and I’ve tried a few other ventures that didn’t really take off or develop much.

• My main goal: I'm working to save up for my main project, which is opening a used car dealership. The used car market in Portugal can be very profitable if done right, and I’ve got the experience and skills for it. However, I need more capital to get started, so I’m looking for a good side hustle in the meantime. I’m willing to put in the hard work and sacrifice sleep if needed. I want something that can bring in decent extra income with minimal risk and low initial investment.

One idea I had was to start a gift box subscription-based online store, but I’m looking for more suggestions before committing. What other ideas do you guys have?
