How much time is needed for retail arbitrage fba?

Hello im officially a Amazon seller after getting verified via mail. I want to start retail arbitrage but i work a lot of hours and am wondering if i even have time now. It seems like getting ungated (even if i pay) is going to take me weeks. I want to be able to pick up a product and sell it but instead ill have to be careful what to choose. Any input on this thanks!?
