I've started a freight carrier business, I've done the process and got the paper work that's necessary when starting up a business, I've drawn up a business plan, profile, quotations, forecasting, I know the relevant associations, now  i'm looking to go out and attract investors or look into other forms of funding for a start up capital. Now this goes out to anyone with experience in this industry, what would you say is the most important thing to know before I go on?
