What to do with side hustle money?

Hello,

I have a great side job (it’s legal, and I have a corporation)

I also work full time in IT at a government union making 100k + pension, benefits, etc.

My wife also makes $66k as an admin at the same union. Same benefits.

We live off our salaries and want to use the side money to pay off our bad debt (11k cc).

What else should we do with it?

We have a mortgage (500k) and car (14k left) but plan on selling soon so aren’t worried about that.

We have absolutely 0 savings but we’re anticipating at least $20,000 by end of summer but aiming for $50,000.

Monthly expenses rn with debt, food, car, mortgage and everything is about $9k.

Any help is appreciated, just trying to figure my life out with this opportunity I’ve been given. I really don’t want to fumble it, I want to build a family with this
