368529 Drupal/Ubercart Ecommerce

I have an existing Ecommerce site based on Drupal/Ubercart and need the code updated on the main page. There are problems with the html and/or script code and browser comparability issues. The first problem involves the rotating banner on the main page. The script rotates 3 banners and for some reason the 2nd. and 3rd. banner appears blank in Firefox version 3.5.5. The problem only seems to occur with this browser. The second problem involves the pricing on the main page. When I update the pricing in Ubercart, the layout for the products on the main page becomes rearranged obviously due to poor coding from the previous designer I hired. I need this to be fixed so I can update my pricing at anytime with causing changes in the page layout. Please contact me for further details and I'll give you the site URL so you can examine the code before placing a bid. I need this fixed as soon as possible. I also hope to also establish a long-term partnership with a good programmer/designer that has experience in Drupal/Ubercart since I will need the site updated occasionally. Please provide me with references and/or projects you have worked on in the past using Drupal.
