To tell you the truth, it is quite hard to find a job in the zoological field (let alone something as specific as herpetology) as there aren't many positions and lots of competition for them.
Most herpetologists work in research, which is pretty practical when you are conducting your experiment/research but there is also a lot of writing as you need to write up your findings as a scientific report and try to get it published in a peer reviewed journal etc. You also need to do lots of statistics to back up your findings.
(by the way, I'm not trying to talk you out of it - but you do need to be extremely dedicated and it is a long haul with no absolute guarantee of a cool job at the end - I'm all for informed choices
)
