Letter of Inquiry for Alfred P. Sloan Foundation grant

I had intended on self-funding this project. The deeper that I get into the research and writing, I am realizing that the costs are quickly escalating. I applied for a grant through the Alfred P. Sloan Foundation for a small grants. As part of the application process, a Letter of Inquiry must be written to the program director. If approved, I would be given the green light to write a grant application. Here is the letter of inquiry that I wrote, minus the recipient name and the project participants.
