What should you look for? I'd say look for nothing but wasted time, energy, and money. Dropshipping is rotten idea.
Only sell what you have in your own hands, so YOU can control the quality of the goods and control the shipping of them to buyers. Because when buyers are unhappy with what they get, or when they get it, or if they don't get it at all, it is YOU who must deal with their complaints, problems, refunds, and negative feedback.
In particular, it is a bad idea to dropship from China. You'll be in competition with all the other sellers, many of them your compatriots, who are trying to do the same. And most of the stuff on offer is rubbish, nothing but overpriced junk and fakes.
