In my opinion your best bet would be to go to
USITT your last year of school to look for gigs. I know that a lot of cruise ship companies, production companies, Disney , Feld and Networks Tours go there to recruit youngsters to work for them. That is how I got started out of undergrad and I went to
USITT this year and it seems that is still the case there with recruiting.
Why they are looking for people that young is another conversation all together.
From what little you just told me you do not have the
current experience to go tour. You can however
build up to it, it may not be something you would be able to do straight out of school. I could be completely wrong and you may be able to do an awesome job. Another thing to consider is not only skill set but also personality and life experience.. You could very well have a rocking skill set but if that is your experience out of school and you go tour and
roll into a city like Chicago or Philly the I.A.T.S.E
stage hands you have on your crew for your may very well eat you alive. 80% of your success on the
road and the industry as a whole is the ability to adapt to different environments and personalities. The local
stage hands don't care if your show tanks and you get fired, especially if you are not cordial to them and you don't take charge. they are still getting paid regardless.
Trust me, I have seen this from the perspective of a touring
stagehand and local
stagehand working out of my I.A.T.S.E local.
An aside, no one cares about what you did in high school, once you finish your undergrad that is all null and void.
