Marc, I make & sell all kinds of jigs, painted & unpainted. It depends on the head style how well the hook might fit, but typically those hook sizes are not used for those weights.
If you want a round head jig, that's probably something that can be done with those hook sizes.
Do you have an exact jig style that you're wanting to get? Even with basic round head jigs, there's various configurations.
This is the yellow chartreuse that I have, I only use powder coat paints, and do have several molds for round head jigs.
The jig shown here is just an example of one style, and I make sure all the hook eyes are clean.
