Build a Small Zen Cart Site - Shopping Cart + Data Entry

I posted a project before similar to this, but this is a more simple project using Zen Cart technology. I am looking for a simple and easy to navigate website/shopping cart in the business of selling brake pads. I have roughly 250 individual part numbers of brake pads. Each part number fits one or several makes & one or several models of each make for a certain year range. You will be required to enter this data from a table that I will provide you. You can view my current site and see how I have a small portion (about 70 Part Numbers) this data in a simple table. Punderstand that you will be required to enter 250 parts in total, not just the 70 listed on the site right now. The site is: [login to view URL] I need to have this data categorized and easily searched by potential customers using Zen Cart software. You will need to have good Zen Cart experience. Please give me your ideas. Thank you!
