About the best advice I can give is that when you reach the point of getting 3,000 to 6,000 babies hatch out per year, right before hatching season, make sure you have enough Valiums available to get you through.
Be prepared to piss people off because you can't do everything all at once and just do not have the time to please everyone.
Forget about vacations. So if you take them now, take LOTS of photographs so that you can look at them to remember how it used to be.
Take stock of your situation and see how many little tiny details that if any one of them goes wrong can sink your boat. Then take another Valium.
Volume statistics and sales stats? Hah! Record keeping will consists of notes you jot down on index cards sitting with the cages the animals are in. Sales stats will be done while you are trying desperately to get your taxes down before breeding season rolls around again in Spring. Normally you will have no idea whether your business is doing well or not until it is too late to do anything about it but only hope next year will be better.
Personally, going into this with the plan of becoming a business is not the best thing in the world to do. Do it as a hobby, and if it does become a business, then just go with the flow with the understanding that maybe you are doing it right and this is the way it should be. I NEVER had any intention at all of this becoming a business. I wouldn't know how to write a business plan if my life depended on it.
