I will give you this piece of advice. If you can, don't saddle a new teacher with being the only teacher who mentors you. Even if you find other non-teacher mentors, it is a big time commitment for new teachers who are generally working really hard to stay afloat that first year or two. (If they only teacher who is willing is a new teacher, then so be it. But try to find some others.) Which is part of the reason so many teachers quit in their first couple of years. And new teachers are generally going to be less knowledgeable about how things work in the school district.

The idea expressed by several posters of involving parents is critically important. You want their enthusiastic help. Knowing that parents are behind something usually helps bring a principal around. The login stuff is not a big deal. One phone call to FIRST from an administrator at your school can generally get that taken care of. You are fortunate that your senior mentor is already contacting you. Contacting the regional director can help too.

One last piece of advice. The more ducks you line up the easier it will be to convince a teacher to step up. If parents can take care of a lot of the management tasks and promise to help, it will make the prospect of leading a robotics team less daunting. Most teachers get a little intimidated. It's only natural. There aren't many teachers who have built and programmed robots before. You need to convince them that it will be fun, a rewarding experience and not too overwhelming.
