These are the guidelines—the rules and regulations. Policies are to clarify expectations on conduct issues, dress code, etc. A good example of a set of policies is what would be in your Employee Handbook.
Be sure that your policies complement your mission rather than compete with it. For instance, if your mission is to provide the most outstanding service experience ever, don’t make policies that are going to frustrate the clients.
You can get an Employee Handbook template for your state. Make any needed changes to it and have a labor attorney review it. The technical policies for your industry may be found through industry associations, etc. Otherwise, you’ll have to write them line by line. Even if you get something that is already “complete”, chances are that you’ll have to invest some time tweaking it.
