Customize e-Commerce website developed using Magento.

Dear Freelancers, Greetings! Wish to Customize my e-commerce website. Please note the site is developed in Magento. So those with good experience with Magento should bid. Will give you some websites to refer (as examples) as how I expect the Results (in a Grid format) along with my own website (which is to be customized). Details: ======================================================================================== There are 2 categories: 1. Loose Diamonds 2. Jewellary The site is developed using Magento. Database, Payment details etc every thing is in place. Changes I wish to make are ...... 1. Loose Diamonds: Currently Search category shows searches for both Loose Diamonds and Jewellary. Wish to remove the Jewellary search from there. Currently the Result Table has certain extra columns (about 3) ; wish to remove them. 2. Jewellary: There are 4 subcategories (Rings, Bracelet, Necklace, Pendant). Currently there is a Search criterion which is exactly same as the one appearing under Loose Diamonds showing Search for both (Loose Diamonds and Jewellary) and Results are appearing in a Table format. Wish to remove the Search criterion completely and when clicked on any of the 4 subcategories ; straightaway Results should appear in a Grid Format and not Table format. ========================================================================================= Thanks.
