I highly recommend a book called "Small Time Operator". It might be simple
but I think it covers a lot of aspects regarding how to run a small business
/star-up company. The link to the publisher is here: http://www.bellsprings.com/small-time-operator.htm
Also anyone who's interested in running a small business should check out
all the info on SBA (Small Business Administration)'s website at www.sba.gov.
