I've used vps6 in the past for reselling VPS and they are pretty decent if you market their servers for a good price then you can make a decent income. They have many special features back then that they should possibly have still today. The more you sell the more you'll save. I started reselling their servers and now I own my own dedicated server selling containers from there.
There are a bunch of VPS resellers with wonderful prices and features. Contact VPS hosts that offer good VPS services and see if they can work something out with you.
Once you get a good income going and if you have personal money you can invest then purchase a nice dedicated server nd from there sell your own VPS servers trust me when you get to that point then you'll really feel like a business and you'll see a lot more income. You just need a certain niche and put elbow greas into your work it'll pay off in the long run.
