Startups are generally told that popularity is a nice problem to have. Further it sounds like you're over-scaling before you release it. I have no idea what you're releasing though.
If you wanted to look at monetisation opportunities, even if it'll cost a lot of money, you need to say what you offer. Then people can say what you can sell. eg Allow people to do 10 images. Want to do more than 10 a day? Premium account! But how do you define a price?
