Thanks for the question.
You can ask for anything, but you will likely not get it. Pray instead that God helps you to find the proper way for you to have a supportive income. Your fear may be that you will not have your needs met, and that somehow a big windfall of money will solve that. That is essentially putting faith in the wrong place.
Money is no savior, it is simply a tool. Jesus Christ is our Savior and He knows your needs. Put your trust in Him, and He will certainly answer your novena with a solution that could surprise you. Just pray for His Solution. You don't know what that will be, so you will be required to place your faith in Him and trust that His Solution is better than yours.
That is a novena worth praying.
