Hello! Personally, I do not like delegation services. I prefer interacting with the community. However, if you want to delegate your SPs, you can use something like PROJECT HOPE. However, I personally find it much more profitable to write posts and communicate with other people. You should find a community that is interesting to you and try to write slightly longer posts. I can recommend you, for example, the WOX community.

By the way, many people are interested in participating in various contests held in Steemit.
