Hi, we want a CodeIgniter website using MVC which will later be integrated by our developers to another CI site. The key features will be: Each user will be able to create a store and manage it with his own dashboard Payment gateway will be only Paypal allowing users to use paypal or credit card Users will be able to make stores favorites and review them after completing orders Billing system to collect monthly fees based on percentages of sales and products Keyword tracking so personal suggestions will be made on users for interesting stores Campaign buying system so each store can be advertised Currency, shipping and terms options for each store Backend to receive payments, manage stores and users More information will be provided on agreement. The budget is this and please don’t bid if you are far from it. The website is a simple store mall and it shouldn’t take more than a week. The general PSD will be given to you ready.
