[Feroz1325]

I believe that our administration helped us out for two reasons, the first being that we are very active in the school community (we demo our robot at almost all school events and act as a huge promoter of our school). Second, we contacted past sponsors and asked them to support us, both in a traditional sense (either monetary, manufacturing or in-kind) and within our school.
If you can show that companies have faith in you (so much so, that they are willing to give you thousands of dollars), your administration may think twice about not supporting your team.
Once again best of luck, if your team would like specific information or help feel free to PM me and 1325 will help as much as robotically possible.
