Ideas on money making activities during down time at new job

I think the custom dash is a good idea as well as stainless exhaust tips would be a good idea another idea would be a custom scoop think 1970 road runner the pop up scoop with the teeth decal but on steroids kinda like a pop up hemi scoop solenoid activated..I would buy that for my dart so I can keep a sleeper look and with two switches run like a beast!
One switch for the scoop and one for the quick-time open exhaust!
I made a drawing and I want to pursue it!
