I think for your business, this site works very well! The font size is a great size and the size of your site(width and length) is good as well. Just as you aren't sure what your viewers resolutions might be. I also like how you made all the links on the links page open in blank. I did find though that the last link does not and you might want to change that.
I do have one question though, the imagery you have on both sides of your header, did you find those on a free image site or did you grab those off of a google image search? If you did the latter, I'd recommend going to: http://www.sxc.hu
It's a free stock photo site and I'm sure you could find some imagery there or try and google for some free stock photos.
For a few suggestions, I think on the main page, the line length should just be a little shorter and maybe the list of the things you do could be centered, maybe? Maybe even the shorter lines after that. You could try it out, I think both work, so you can make your decision on which is best.
I also want to congrat you on underscoring your file names, instead of using spaces!
Good luck with your business and your web site!

that he can outwit Nature and more time tasting her sweetness and respecting her seniority."
