Sorry, but I find it hard to sympathize with a team that spent $23,000 in registration fees alone and pays their mentors asking for money.
Seriously I'd echo many of the previous statements. Look for local machine shops that may be willing to sponsor you or let you use their tools. Many college machine shops may also be willing to produce a part or two for you when needed.
Perhaps look at re-allocating where you spend your team funding to reduce the travel costs, and allowing for more to be spent on tools and parts.
