Dear Ms. Robles,
As satisfied customers of Firmament Financial, we of course look to you to help us save for our upcoming child’s college education. We feel that we can afford $100 per month for the 18 years until college in your College Savings Plan. We have a list of universities that we have researched with the approximate cost per year for each. Which if any of the university options will we be able to afford for our child? We would prefer to send them to an elite private university if we can afford it.
