Runnin' a hoe & other equipment is a skill. I bought one 3 years ago, have good hand to eye coordination & it still took a bit of learnin.
I imagine you could find another job fairly soon. I'd hold off on sellin' the load stuffs but I'm not you or in your shoes.
Wouldn't make it known to employers, co-workers, or clients if you carry. Do so discretely & it likely wouldn't be an issue. If your not breaking the law the most they could do if found is fire you.
Being self employed is a double edged sword. I find it worth it. Even still a few client properties we can't carry on, that's what blades are for. You must be motivated, smart and /or a gluten for punishment.
Best of luck crossing a new threshold.
