Source Phones for Arbitrage with £200+ Profit Margin

I'm looking for a skilled product researcher or virtual assistant with experience in online arbitrage, preferably in electronics/mobile phones.

The Task:

Find mobile phones available on ANY website worldwide (can be UK, EU, Asia, etc.) that can be bought and resold on the French website https://www.cashexpress.fr

Use the prices from cashexpress.fr as the resale value.

The phones must be identical in model, specs (storage/5G/etc.), and condition.

I need a minimum €200 profit margin per unit after accounting for all costs (purchase price, shipping, taxes, etc.).

You must provide:

Name of the product

Buy link

Buy price

Resell link on cashexpress.fr

Sell price

Profit calculation

Ideal Candidate:

Has experience in retail or online arbitrage

Knows how to use tools like Keepa, manual search, or price comparison engines

Can spot fake or scam sellers — this must be legitimate sourcing

Preferably speaks French (optional but helpful)

Note:
This task can lead to long-term work if successful. I'm open to arbitrage opportunities from any country, but ideally, the stock is within France or the EU for faster processing and easier resale.

Budget: Open to proposals — this is a research-based task with potential bonuses for high-profit finds.
