How to become a professional Minecraft modeller?

I love modelling buildings. Not so good with redstone but I could improve with time. I have made many static structures such as apartments and offices complete with detailed floorplans. I was wondering if there's a degree program where I could model buildings in Minecraft professionally? Like you work on a project and sell the rights to the model or you make it to someone's spec and they pay you for it? I would love to quit my day job and do this instead!
