120396 osCommerce Customization

I have an OsCommerce website which I need a few things. For one, I need to add a Flash slideshow as well as change a few design elements, such as make a horizontal row of brand names into a vertical column of names. I will also need to have prices that say: Retail Price: with a price striked out and below that something that says Our Price with our price. Also, our products come in a variety of colors so I will need to have small thumbnails of our product in the various colors and when someone clicks on the thumbnail, the main image will change. I will also need for the customer to be able to choose the product in different sizes, however, for this there is no need for a change in pictures. Let me if you are interested so I can give you the link in the PMB, also if these things are too complicated for OsCommerce, let me know so we can work on perhaps having a customized script. Thank you.
