Hey Leon!
Actually there are many ways, you pretty much just need to find somebody who wants to delegate to you.
Hive account@blocktrades and Hive account@minnowbooster are the most popular ones who lend SP for money!
But there are also whales supporting minnows by delegating to them - But that's rather lucky to achieve.
Or you make a personal deal with a whale!
Hope this helped you ;)
