I wouldn't plan on it being your primary source of income but why not give it a shot now that you are in.
They key is to find the right niche in the hobby through market analysis and produce animals that others want. You have to offer something no one else has or there is a very limited supply of. Enchi's were hot this year, Mojaves last year, Pieds and Albinos are always a good seller. Woma's probably not as hot.
You need to spend lots of time on forums, checking classifieds, talking to breeders at shows. It becomes very time consuming.
How many people are throwing 25k at a banana? I don't know but if I could I would.
People enter and leave this hobby everyday. If you can can produce quality animals and provide excellent customer service you can be profitable down the road. Profitability does not happen overnight ask Donald Trump or Bill Gates but you have to start somewhere.
No matter how bad the economy is people will always have pets whether it is a dog, cat, or a reptile.
Just my two cents.
