A couple of quick comments.
#1 - loose the underlines in the left hand column links. Home > Design > Site Design > Styles > fonts > Left Column Links (normal) - choose bold instead of bold underline.
#2 - Try to choose a set height for all your thumbnails. This will make the rows on your front page and category pages even. I would make most of them a lot shorter. The Aqua Sensor you need to make taller - just add white background around the top and bottom.
#3 - Indent your center page. On your Extech Pocket Moisture Meter page, the features circles are in the left column.
#4 - About Us page. Set the margins so that your paragraphs stretch down the page more. The page looks too short. Look at what others on the forums have on their pages.
#5 - You might want to add images of payment and shipping options to fill in some of the empty spaces.
#6 - I have been starring at the monitor all day so my eyes are tired ... but the Search Products being in italics seems to make it blurry.
#7 - Your part numbers are just a tad too light for laptops. If a company wanted to buy from you and had to put in a requisition to their sales department, they'll need that part number.
#8 - Add your hours on your contact page so people know when to call.
This are mostly minor things that can easily be fixed. #1 and #2 are very important (in my humble opinion) if you want to look more professional. But you are a long ways up from looking like a 'Mom and Pop' site. The colors you have picked set you apart.
Oh ... and while you working on the look, start working on your SEO. Your meta description for the Extech Pocket Moisture Meter doesn't even mention those words in it. And be sure to add your company name to the title of your home page. Also, you need to have Netsol set it so that all your pages come up with the www. on them. Some search engines will treat www.yoursite/index.aspx different than just yoursite/index.aspx.
Best of luck and have some fun. Your site will never be finished and you will never be bored (IMG:
