I have a couple suggestions, and I apologize if they were already covered above. It looks like you used SiteBuilder to create the site, so I understand that there are probably some limitations on what can be altered.
Overall, I think the brand and the design is strong and I love your logo. I think with a few usability tweaks the site will perform very well.
I like the modern clean design. I would add a phone number at the top of every page and maybe user reviews on individual products and tell a friend feature. Also on the product images. Would it be possible to http://www.modernmini.com/nursery_files/nurseryfurniture/nur seryproducts/nfTAoibo.html
have the images when clicked on to become larger show in the same screen instead of opening up a new page?
I really like it as a consumer it is not intimidating at all. If you plan on using Google Adwords you might want to consider using there Google Checkout as they are offering free processing on all orders through Dec. 31. Once that is over however for every $1 you spend in adwords you get $10 in free processing charges. Which I think would help you out w/ your big ticket items.
Hope this helps,
