Building citations for multiple location business?

What's the best way to do this? Say you use the same citatioms from the top 100 sites for each location, how can you get them posted without? Would there be problems with duplicates etc? Would it work if each location was based via sub page on Google Places, then via subpage on citations?

Here's how it works: Stay consistent. When I do this I treat every location as its own entity. There shouldn't be any duplicates even though the business name will stay the same, the address and phone number will be different. If you want to outsource this send me a pm.

Like zombie said, you should just treat each as its own entity. Do a different submission for each. Get a different Google Places page for each. And mak sure your Name, Address, and Phone are correct for each location.
