Circus....
I did not view all your pages... and although you probably have some good products for sale, you are not doing your products justice with your site.
1. You need a site name and logo on the top of the page... and this information should be on every page for consistency. YOur home page is title as "welcome"... contact page title as "Contact Us...
This kind of structure is, unfortunately, a result of using Front Pages themes.... there is no flexibility for change. I suggest you either not use a theme (i.e., start from scratch or purchase a template)... you can find some nice templates for FP almost anywhere and some are not expensive... if this is to be a serious venture for you, I suggest you invest a little money into making your site attractive and informative. You can try looking for a template at:
www.pixelmill.net
(p.s. I have no self-interest in this site, although I keep recommending it.... only because they have the largest selection and their prices are reasonable).
2. The photo you used on the index page is not clear... it looks as if you re-sized it and therefore, the resolution is not good.
3. The first thing a visitor should see is complete and concise text explaining who and what you are. you have 5 seconds to tell your customer who you are... your physical address should not be the first thing they see.
4. you have too much on your index page... try breaking up that info several pages... most people would prefer going to another page rather than scroll down.
5. your color scheme is too bold.... I don't feel orange is a good color... to view an article on the phychology of colors, go to:
www.templateresources.com
click on "articles" on the left menu and look for the one about colors. (BTW, they also sell templates for FP [and cheap], but if you're not a seasoned FP user, they can be difficult to use and their support is not very good).
6. get rid of the hit counter... it is not professional. It is showing different numbers on each page, anyway....
7. on your "What's new" page, you created a table that is larger than the size of your site....
8. you should use a more professional font... try Arial or Verdana... and use a 10pt (size 2) font throughout your site..some of your font is too large..
9. For shopping cart info, you can use PayPal, which is free... or you can check out 2.checkout.com (which is reasonably priced)...But adding a shopping cart should only be done after you have fixed your site...
I think your meta tags should also be worked on, but again, only after you have worked on your site.
I don't mean to be hyper-critical, but if you want to make a sucess of your dollhouses, you need a better presentation... as it stands now, you site looks amateurish....
Hope this helps... and good luck!
