It is a logical strategy to increase the size of your potential markets by extending your geographic reach. Your ability to increase your geographic reach is dependent on a number of factors.
The first is your ability to serve your clients without being geographically close.
Another is your targets' perception of how close they think they need to be to you. While you may feel comfortable serving your clients from a distance, your prospects pre-conceived expectations may be too deeply entrenched.
Another is the cost of travel or satellite office space if you need to have face-to-face meetings.
With current technology, you may be able to serve clients that are at far greater distances than you had previously imagined. You should periodically consider your geographic reach as your situation changes.
