A friend of mine (honestly, it is for a friend) has been taking calls for a local book. he is interested in branching off on his own and starting up on his own. the problem is he needs a financial backer to get started. he asked me. i dont know much about being the book, he says he could get about 100 guys to start. how much would i have to start with, approximately. is there any thing else i need to know?
