Thank you, I appreciate that.
I've been making and selling miniatures for over 4 years now. At times I've managed to make a living and at times the mere idea of a minimum wage sounds like a rich mans world.
I don't want to turn you away from your dreams, but it is or can be difficult. Make sure you have at least a secure part time job before embarking on a career of producing and selling miniatures. Prepare for expensive mistakes in failed moulds, lost post where you have to pay for and re-send packages, insults and competitors that are quicker than you that would jump onto any bandwagon you happen to create that seems popular.
My simple advice to start off with would be to initially sell your miniatures to other companies, take on commissions. In your own time make a set of miniatures, get a mould made and sell the casts privately on FB or something to get a little bit of experience. Dip your toe in before taking the plunge.
