Hi K--
Just my opinion--but I think your request for immediate services should be in the very first paragraph. The letter is lengthy, and you don't want the point to get lost if a judge merely glances over your writing.
I might also condense the financial issue to a single concise paragraph where I explain that the time caring for this boy interferes with the ability to work and to afford to provide more extensive services yourself. You don't want it to sound as though options are available but you'd rather not pay out of pocket. (I understand what you are saying completely--but sometimes it does not occur to well-heeled judicial staff that you really don't earn enough money to cover these kinds of expenses).
Just my two cents--
