Magento - Product Attribute Upload & 2 other simple tasks

We have a new website with about 189 products. We need the attributes for these products added/uploaded and associated with each product. We also have a couple other simple projects. Here are the specifics: Task 1 - You must have experience with Magento, including the specific work listed below. We have a spreadsheet listing the size and color for each product, one product per row with product id. - You must have an understanding of uploading attributes. - You must understand how to create attributes and attribute sets. - You must understand how to create a configurable product or grouped products so that the size and color can be selected in a drop-down by the customer when they are adding the product to the cart. - You must complete and test your work completely. Task 2 - By default Magento shows black around product image thumbnails. We have attempted to change this following some forum postings but have been unsuccessful. We need this black removed or changed to white. Also need to have you check the image size setting. Some of the images are pixelated probably from incorrectly setting one of the dimensions. Task 3 Update a few colors in the stylesheet and font sizes in the for items in Cart and a section of links in one other area. Do not bother to bid on the project if you do not meet the requirements.
