Electronic devices sourcer

I’m looking for someone to help me find electronics (like phones, tablets, or audio gear) that I can buy cheap and resell for a profit. My goal is to make at least £250+ profit in total after fees and shipping.

What I need from you:
• Find deals on electronics that are selling below market value
• Check resale prices on eBay, Facebook Marketplace (UK) vented, depot
• Make sure there’s a clear profit margin
• Show me 2–3 good options to start with

Experience in product research, e-commerce, or flipping electronics is ideal.

Let me know if you’ve done this before and how you would go about it. This could lead to more work if it goes well.
