Create a product list to import into our Magento store approx 450 products

We need to import around 450 products to our site these are a mix of simple and configurable products. The website is a magento store

The products are grouped together. On some you will need to set a main product and then configure the colour variations of that product. Its fiddly work but shouldn't take more than a few hours. We have the file fields set up, and the correct image names etc, it will just be your job to put it all in the right places and check that the right details are listed with the right product number.

We're also open to ideas if you've worked with magento before and know a faster way.

The product may need to be fully configured in the magento admin after, linking products together (there are around 40-50 products that will need to be linked to their colour variations) Please let us know if your quote includes time for this part of the job or just the import file creation
