Custom Product Import into Magento Store

I'm looking to create a custom extension that would allows me to import products easily into Magento stores. I'm open to ideas and suggestions how this can be done. At minimum this extension should accomplish the following: --I can enter a product URL from any e-commerce site and the product title, images, price, attributes, etc would automatically be imported --I can modify price, for example increase all product import by 10%, for add $10 to each product imported. --I can enter a category URL from any e-commerce site and all the products from in this category will be imported to Magento store. --Summary of product import session (how many products were imported/completed, how many failed etc) I'm looking for creative ideas to make this work. Please send me your bid and bright ideas :) Thank you! I can be reached on [Removed by admin.
