If you really want someone who is going to 'dropship' you profitable phones/items and be reliable, are you *seriously* going to rely on someone who comes to you and starts telling you he can do it?
If you want to make money, you need to put in time, research - and look for yourself. As the saying goes, if it sounds too good to be true... you know the rest.
Find a drop shipper that you deal with directly, not a guy like this who likely is a middleman between you and the real drop shipper. Yeah, he has 'warehouses' all over the world, yet won't reply or give any prices out - very sus.
