Nice job. I recommend you drop the Flash intro. Those things are just window dressing and ego boosters for web site designers. Remember when web sites had all those little animated gifs thrown into them just for the sake of having them. Do a test, put a hyper link at the end of the flash intro to enter the site, move your skip flash intro link down farther on the page and check your log files to see how people get off that page, less then 5% of visitors will sit through a flash intro anymore.
Cut up your main graphic called frontimage.jpg into smaller images and put it in a table, have it optomized in photoshop. 111k is a ridiculously large file, you should be able to reduce it to 20k easily, cutting loading time by 3/4 for dial-up. Actually you need to optimize all the pics.
Put text links on the main page so engines can index the rest of the site. You need return navigation on all the pages inside the site. Those are all minor things in the big picture. 90% of clients should be pretty happy with what you have there.
Here is a really good site that is in the same biz model as yours. http://deserthighlights.com
The stong suit to their site is the trip reports section. Probably the best I've ever seen online. They've got it in a good format and have executed the idea very well.
