You've waited an awfully long time to pursue help in the matter. Next time, please don't wait to realize you don't have enough funds.
There area couple things you can do.
1) Get in touch with the MAR people and with Don Bowers. Scroll down on this page
http://www.midatlanticrobotics.com/who-we-are/ Don should be able to help you out.
2) Also email
frcteams@usfirst.org addressing your issues/current situation
3) If the above two don't yield results in time (which I doubt will be the case), consider using your funds for VEX this season. Use the year off to gain sponsors who can support your team and won't let this happen again.
This is why FIRST is a year long fundraising effort. Please don't wait until the last week to realize you lack the funds to participate.
Brandon if you guys need any help, drop me a line.
