Changes to OSCommerce Site

I have an OS Commerce site that has been customized. 1) I, as the store owner, upload my products via the admin section. Outside users pay a fee to upload products and they have a page where they upload products. I have attached a screen shot of the page where seller uploads a product. I need to make some changes to both sections.. both my admin section and to the page where a seller uploads their products. On the seller page I need to the following changes: I need to change the phrase "Actual Size" to "Size as Listed on Tag" I need to change the phrase "Product Name" to "Product Title" and I would like in parentheses (ex. Size 2T Baby Gap Red Skirt) Remove the field for "Weight" On my input page in the Admin section, I need the following changes: Add a field for "Main Color" Add a field for "Size as Listed on Tag" 2) In the Advanced Search feature that comes built into os commerce, I would like for the user to be able to search by size and color. Can these be added to the advanced search feature? Please ask any questions that you feel are necessary. I want to make sure I'm explaining the project exactly. the name of my site is diddle dumplings dot com ## Deliverables A screen shot of the seller's input page is attached.
