Your dilemma is not uncommon. In fact most, if not all of my clients, initially underestimate what an undertaking building a quality website can be. They say the same types of things about interactivity and features: they don't want any. When they see what that means to a developer and designer they are wholly unsatisfied because we are not really speaking the same language. Having links change color on mouseover is interactivity for example.
Web sites, like cars, can be had within a wide price range. For the most part, you get what you pay for and need to set your budget accordingly. You can get a Chevy Aveo site for $300, a Toyota Camry site for $1,000, or a Porsche Carrera GT for $20,000.
The Aveo site will have a color scheme that doesn't make you sick, but doesn't inspire confidence. Page layout and navigation will have big gaps. Your attention will be drawn to places it shouldn't be making it less likely that users will read your content. Every once in a while you'll find yourself at an error message instead of the "thanks for your feedback" page.
The Camry site will please Google, present your content in a non-offensive way and for the most part be entirely forgettable as it looks and feels like every other site.
The Carrera GT makes your site a destination in and of itself with pleasing navigation, intuitive menus and a gorgeous layout with complimenting color scheme. Ten minutes after a site update, your new content is the top link on Google. Users will return often even if nothing has changed.
There are some unscrupulous firms that will overcharge you, but for the most part reputation and integrity are as important to them as it is to you. So, set your price range.Google "web designer" in your area. You want these people to be local to minimize hassle, and to reduce any delays caused by inevitably miscommunication. When you find like 5 or 6 sites, look through their portfolio sites. Ignore any that are no longer using the design that company made and any designs older than a year. If anything feels awkward, blows up, or just plain doesn't sit with you, move on. Choose the company that you think will best represent your brand online and haggle over the price they quote. No hand holding, no extra time needed.
For 10 pages of static content and a good, brand-appropriate design I would expect to pay around $2,500 - $3k for a US company to complete it in 2 months. Thats mostly for design work, with implementation being billed at between $80 and $100 per hour. Flash, Ajax, or server side scripting (blogs, calendars, etc.) would of course take longer.
Can you learn to do this yourself? Perhaps. But it will take you a while to grasp CSS and semantic markup and even longer to understand the principles of design.
