If you are looking at acquiring your snakes as an investment, you might want to heed the above advice and get several cheaper female morphs. You will have a much easier time selling less valuable offspring and can build a reputation. No offense at all, but I personally wouldn't buy a 5k morph from someone new on the scene with no reputation. I would, however, consider buying a $500 high quality morph from said person.
Also, with one female, you are literally putting all of your eggs in one basket come incubation time. Better get that down perfectly.
