I jumped the gun and missed the whole point of Larry's first post!
Yes, Larry, of course you can do the same thing.
You have the skills, the tools, you know the pitfalls and the hurdles you will face. You certainly can market to local businesses the same way.
Now, is that the best way to approach it? that is another question. But it is a GOOD way to get going, and it may be the BEST way for YOU to start your venture, because of your experience and that you will be in your "comfort zone."
