Business and Finance Forums

So i'm basically starting a Plumbing Business, I have my license and everything and now I just need to get started. I don't know where to start though. I want to advertise on the web and papers but I don't know how to start. Any advise out there for a beginner. Like what is the pricing with all of that. I have these people calling me telling me they will do the advertisement for me, but I'm looking for a cheaper way. I know you get what you pay for so I guess if theres no back route for then Ill just take there proposal
