Thanks for your inquiry and what a beautiful affirmation! Clear Quartz points are great to program with your affirmation and intent and then place in a grid. You can alternate Clear Quartz with Citrine and Aventurine, two great crystals for attracting abundance. A crystal in a pyramid or generator shape in the center of your grid will also help to materialize your affirmation.
One suggestion for the wording of your affirmation is to change the beginning from "I see myself..." to "I am..." as the most powerful affirmations are worded in the present tense. Here is a link another Healing Crystals Consultant wrote on crystals and affirmations that addresses this and offers additional crystal suggestions:

I must share the standard disclaimer that I am not a doctor and cannot give out medical advice. Crystals for healing should be used as a complement to other therapies and not as a replacement for regular medical care. The information offered here is based on a combination of my own personal experiences and that of others on using crystals for healing. My hope is that you will let your own intuition guide your path in working with crystals as well.
