As I said - take a pause.
These guys are some of the best people you could get advice from if you choose to make the hobby a part of your life. I'm not exaggerating when I say the years of reptile keeping experience shared between the posters on the thread is best thought of in terms of centuries instead of years. The main triggers to us as long term keepers was mainly the vagueness in species and the idea of money - that's what lead to this going south.
Take time, read everything you can, and find the snake you like -then the practical questions you ask won't be so "red-flaggy" [ hey I just invented a term] to the forum in general. 20-40 years is a long time to pick up poop from an animal you don't love.
And if you don't love them I can guarantee you will sell up long before you make a dime. And that's the honest truth.
