Since you are new here, I suggest you give out free vouch copies and build up a portfolio and reputation, like many others did. Designers here are very competitive and you need to have samples of your work to even attract viewers.
Just take a look around the service sections, and check out their threads and designs, which may get you inspiration as well. And since you can provide other services too, you should add them to your thread title, or create a new one in the future.
Best of luck!!
