Hi, I've a new magento website. I need someone to custmoize my shopping cart for me to be able to add the products. Pleasse study carefully my website, go to the "commander" link, (means order in english) you will see that I have 9 main products. I need someone to fix some bugs on the shopping cart system, and then I will start adding my products by hand. I need this to be done quickly today, or tomorow. Then i will check the website, the product and see how it works. I need an expert in magento, so please show me the others website you did before. here is my website : [login to view URL] After this project, I will need more modification from you, but that will be in other projects, so please bid only for the integration of the products.
