If you want to manifest abundance, you must open your mind.
First to the possibility that material items and money can come to you from both conventional and surprising, unexpected ways.
Second, you must open your mind to what abundance really means. If you had more money, what would you do with it? Take a trip? Go out for food? Get more clothes?
Those things can find their way to you without money changing hands. Money is just a form of creative energy. It is what it can do for you that makes it valuable.
So what do you want your money to do for you? Your Angels will be happy to send it your way if you ask them to.
