To break even or make a profit you will need to make a good investment to do that you will need to know and understand the market.
To me my goals when I started (10 years ago) were two things, produced the animals I could not afford and have a collection paying for itself at some point, I reached those goals and more I have been making a profit for several years however I chose not to do that for a living.
So it depends what you want to get out of it, fun experience not caring if you lose money, produce cool animals and have a collection paying for itself, produce cool animals and make some extra cash, or make a living at it.
And if you invest in single gene like Mojave, Pinstripe, Pastel there is hardly any return either we are talking about animals between $25 and $75 which by the time you will produce some will have dropped even more.
If you want to get a good start investing in a 2 to 3 gene female is where I would start and than in about 12 to 18 months get a male, the most gene you can afford, again it's about knowing your market, and of course it will have to do with promoting yourself as well, even if you were to buy and produce expensive animals selling them if no one heard of you might not be that easy.
