Why don't you pay users for their SP Delegation. I hope it will help you in getting more SP and that will help in scaling. You have chosen a very good price range and giving nearly 300% upvote. Stay with this price range and try to get more sp from users, split 50% of your earnings between the users who delegated you and rest 50% you can take to purchase some SP.
