Amazon FBA Online Arbitrage UK

Hi I am looking for someone to do product sourcing for my amazon FBA store, the job is based on an amazon business model called online arbitrage which involves sourcing products from retailers within the uk. This is different from amazon fba wholesale so I would like to hire someone that has experience with this way of business.
Please let me know if you have experience in sourcing products for amazon fba via online arbitrage.

Thanks
