I need to raise fund to start a non-profit

I need to raise $5,000.00 (USD) for the establishment of a new non-profit organization. I want the freelance fundraiser to make this happen. I would like to understand how it was accomplished. I have not the experience, and this is a new learning experience for me. I am looking for an "all-in" budget, and not an "open-ended" work-for-hire. I am especially interested to know whether this person is willing to be paid based on a percentage of funds successfully raised once the target goal (plus the contingency) has been reached.
