Let's get real for a moment.
One of the first things you should check when you're looking for a web developer is their portfolio. Of course you'll see the quality of the their work, but you'll also get an idea about their level of experience. A web developer who claims to have been in business for a long time should have a portfolio that supports their claim. A web development portfolio with four or five web sites does not demonstrate experience.
Since 1994 we've created more than 250 web sites. We stopped counting at 14,000 web pages. We have 193 of those sites on display here. That's more than 20 new web sites launched each year, or between one and two sites each month. Not only do we launch one or two new web sites every month, we maintain (to different degrees) about 50 web sites for our clients.
