While other photographers, magazines and Internet forums can be useful sources for legal ideas, you shouldn't make key decisions without consulting an attorney. Your attorney should review all your contracts (you do have your own, don't you?) and agree to defend them. Similarly, all businesses benefit from regular accounting advice, if not complete, regular reviews. The first hour of consultation is often free with both attorneys and accountants, and during those first meetings, you can get an estimate of your annual costs for their services.
