I second sparky's reply. The more things you have in place like supply accounts, relations with builders (if you choose to go that route), buisness bank account etc. the easier it will be when work starts rolling in.
Develope a buisness plan. Invision how you are going to handle situations as they arise. For instance what do you do if your supplier limits you account to $500 to start. Your first big job requires $5,000 in material. You should have thought that through long before it became a problem. If you did then you already know how to handle the situation.
Good Luck
