how can you make officiating full time job

[rookyref]

i am a new official who loves his job and has decided that i want to make this a career i wont work high school ball til next year and wish to get in as many games at any level to gain experience
i also value opionions and tips from you veterens who do such a great job in a field where the best recognition is from little to no praise and every call you make only gets at best 50percent positive feedback
im ok with that my skin is getting thicker every game i do
so where should i go to earn extra dough durning spring and summer
thanks pros
