Nice that’s a good move. I know a guy that did that to find what products were popular, then eventually switched to his own branded stuff and built a whole brand.
I haven’t done dropshipping in a few years, I don’t have any recommendations on specific suppliers, the way I found mine were either by googling and pitching companies I thought would be a great fit, and on occasion by introduction through friends or a random meeting at a bar one time.
The only thing I would say is make sure you have a solid plan and either a website or a nice slideshow to show why you’re worth their time. I used to own a brand and we worked with some dropshippers, and some of them wouldn’t sell hardly anything so it was a losing relationship, that taught us to filter applicants better, and if we were unsure we would just give them a discount of like 20% or something for them to test the waters, then they would just buy off our website with their discount code. That might be a good way for you to pitch companies that aren’t interested in bring you on fully into their system.
It’ll take some time to get dialed in but it’s doable. Good luck!
