So for a few years now I've had a side hustle of doing custom scale model cars (hot wheels to be exact) and I've made decent money at it. I've taught myself how to paint with an air brush and a full size paint gun and am confident in my skills. Some of the other things I plan to do are as follows:

Custom model cars (already mentioned/proven) 3D printed items Dioramas Resin art Custom painted wall art

My biggest problem is I work 60 hrs a week and I don't have enough saved up to quit my job and take a run at this full time. I can take a loan but not sure I'd that's my answer or not. My next big problem is I honestly don't know what my potential income could be. I have a guess but a guess isn't really reassuring.

Any tips or advice would be much appreciated.
