A lot of good recommendations so far. I have a few
1) I agree, a lot of the photos need to be redone. Some shots of equipment look dirty, scratched, etc.
2) When I click a picture on the page you linked to, which opens a larger view, it completely takes over my screen and its not obvious how to reduce it, close it, or get back to the base page. I am running 1024x768 resolution on this monitor here. A good rule of thumb for web pictures, is keep them below 800 pixels wide for a full view image.
3) the domain name b-p-t.com is an obnoxious domain name. You want to avoid dashes whenever you can. Its fine if there is a link to click on, but try giving out your domain name verbally. You want something easy and clean for people to remember. (I used to support domain name registration for 5 years)
4) didnt get a chance to really navigate around yet.
