I believe that you want to build an Online Marketplace with similar features to Ebay. We propose to build your website using Custom PHP with an MVC Framework like Codeigniter to ensure SECURITY of your site from various attacks and provide SCALABILITY for future. Of late, Open Source CMSs have been found to be vulnerable to bruteforce attacks and session highjacks, thus for security concerns we would recommend you to opt for Custom PHP. However, we are open to your choice of CMS.
If you opt for Custom PHP, we will provide you a Custom-built CMS with an Administrative Panel to manage, add, edit, delete all the contents of your website. We will use latest Front-end development technologies like HTML5, CSS3, Angular.js, Node.js, JQuery etc. to craft a visually stunning design which will be responsive (mobile friendly) at every pixel.
Your Marketplace website would consist features like the following:
-- User Login/Registration
-- Buyer Section/Dashboard
-- Seller Section/Dashboard
-- Various Categories/Sub-categories
-- Advanced Search & Sorting
-- Product comparisons
-- Shopping Cart facility
-- Online Payment gateway system
-- Order/Shipment tracking system
-- Responsive & User friendly design
We will also assist you to Launch the website and provide you 3 months of Free support after launch. We are a 15 year old Organization based in Largo, Maryland, USA.
Looking forward to discuss further with you soon.
