Adding a bullnose bit to the easle and doing reliefs

I have notice on ebay that they sell reliefs that require a 1/8 inch bullnose bit. I really want to learn how to do reliefs with my carvey, I’ve had one very kind person trying to give me direction on how to do reliefs, but I’m a slow learner. So I have two issues here, one adding a bull nose tool to the standard selections and find someone who already does reliefs with carvey and the 1/8 inch bullnose, who might be willing to get paid for creating a design.
I like the Vector Art 3D set up but I can’t seem to get it to work with fusion and I would much rather pay someone for the g-code if it’s not to expensive.
