I don't agree. The way you choose to present your work conveys a lot of information to your clients. Look at other galleries on the Internet. If you don't have the time to learn the fine points of site redesign, consider contacting a professional for help. If you don't want to spend the cash, approach the designer about bartering some of your work in exchange for the look you want.
Testimonials can be very effective.
Have a page of endorsements from people who love your work. Include a feedback form, and make it easy for your visitors to add their comments. All those things should be mentioned, and can add credibility to your web presence. There is no need to overwhelm anyone with large amounts of information, the web is a layered media. Use links to guide the curious to ever greater levels of detail.
