Web sites are work and most people don’t realize the work that goes into them. Some think they can call a web development company and say “here is what I do build me a website”. If you do that you will get a web site but most likely it will not be what you want. As web developers we can’t possibly know every industry out there or be able to accurately depict what you do in your office even if we know the industry. So you must be involved in the build process so your personal insight and preferences are reflected. No self-respecting business wants a site like the next guy so take the time and get involved with your designer. You both will be much happier in the end.
