Good product + good customer service = very busy. 8000+ e-mails a month? Sounds like you're gonna have to hire staff, or if you want to keep things smaller, invest in a good web design that will help track customer questions and orders without so much searching back. How in the world do you get any production work done with all these other demands???
Sounds to me like there is good opportunity for dramatic growth if you can manage your orders without offending potential customers. Personally I always have doubts about placing orders if the proprietor gives me the impression that my business is 'inconveniencing' him. Unless you have a monopoly, watch the tone of your rules.
