The idea of utilizing an advertising agency that is not located in your same area as where your business is located is a grave mistake. There are problems that you are going to need to deal with that would not present themselves if you could meet the agency in person, and have ongoing interaction with them that is not over the phone or through email. When it comes to verifying the work in a proof, or making sure that everything is being handled correctly, an in-person meeting is always far more productive than a phone call. This is why we suggest using a Las Vegas advertising agency if your business is located in Las Vegas, or a Boston agency if your business is located in Boston. That way, you will know exactly the status of all projects, and can see exactly what kind of work is being produced, without wondering if the person at the other end of the email is even reading what you are saying.
