I am looking for my first job?(what are my chances)?

I am 16 ( currently in school) and am starting to look for my first job. I always get either A's or B's in school. I have been student of the week twice and once student of the year for social studies I have volunteered on occasions and have about 3 recommendation letters from volunteering. I also have a recommendation letter from my accounting teacher. I am hard working, confident, and will work until the job has reached perfection.

So 1.) what are some jobs i should apply for?

2.) what are my chances of getting a job for summer?

3.) should i apply right now in advance for summer break or would it be silly?

Any other advice will be much appreciated

thanks
