I'd recommend focusing on graduating from high school and getting into a good college music program.
Study with the best teachers at your disposal - even if they aren't teaching your instrument. This is how I got into percussion and single reeds - I went with the best teachers available at the time.
As to pro gigs, study with the best teachers in your area - they are the ones getting the pro gigs. I know them and worked with them in Waterloo and the region. There are some serious players in your area, study with them and get them to know you.
Beyond that, keep on studying and playing and if you get asked to do a pro gig it will take care of itself - for better or worse. You are either ready or you aren't.
Education: the path from cocky ignorance to miserable uncertainty.
The chains of habit are too light to be felt until they’re too heavy to broken.
