Revise the paragraph to create a more confident, less presumptuous tone.
If you believe my proposal has merit, I hope that you will allocate $50,000 for a pilot study. It's possible that this pilot study will achieve my profi t estimates so that we can implement the idea in other locations. Even though you have several other worthwhile projects to consider for funding, I know you will agree the proposal should be funded prior to January 1. Please call me before the end of the week to tell me that you've accepted my proposal.
