If you have 35k to spend to begin this venture, I would do the following:

Split your money evenly, into five parts, IE: 5k per animal.
Then I would determine whether I want to raise my animals and start with higher cost hatchies or start with lower priced morphs that are already of breeding age, so you could begin now.
Look at the morphs that are priced accordingly, pick the ones you like the best and begin.

Keep in mind that sometimes you will not sell a snake right away when they are ready... so it should be something you are interested in. That is what it is so subjective. People will always tell you to breed what you want to breed, because there is no cookie cutter response. There is no... A + B = Ultimate Profit.
