Nice initiative, it's good to help people out like this. I remember someone sponsored me when I was just new, and although 0.01$ upvote isn't much, it is a great way to feel supported.
I hope you get to support someone with this, I don't think you should choose me as even though I'm only on Steem since 3 months, there are people who can use the support more than I can.
Keep it up!
