Build an Integrated Online Marketplace

We need to create an online marketplace for merchants to promote their businesses. We need a smart cost-effective team to serve as our key strategic technical partner in assisting us with the development of our eCommerce project which is simply the creation of an extensive marketplace integrated with excellent customer support system. We intend to develop this project in Php/MySQL on laravel framework. We have identified about 5 key modules with multiple and different extensions and features; and we require a very reliable strong technical team to assist us in the development, implementation, integration & customizations of these concepts and features that meets our entire requirements. We require our marketplace to be able to handle the following objectives: 1. Help buyers and sellers of products network and transact through the site such that merchants/sellers can sign-up and create storefront(s) to display its products; and users/buyers can signup/login to make purchases. 2. We need your team to implement a simple way by which Events promoters (Cinema/Movies house, Concert/Shows, & others) can sign-up as merchants and (or merchants can) create a section to enable them sale their respective e-tickets to users/buyers.
