Hi,
We are developing similar marketplace so that'll be very much helpful for both of us to work on your requirements, will reduce the timeframe as well cost, hope it's quite clear with our advantages.
Our recently similar awarded project:-
https://www.freelancer.com/projects/website-design/Develop-full-Bids-web-app
I am enlisting the workflow of the proposed website, will be able to send you a detailed proposal once communication is initiated by you.
The website will be aimed to provide an online marketplace for shipping services, where employers will be able to post items they need shipping in a variety of categories and employees will be able to search & browse through the jobs and can bid on the projects. In addition, employers will also be able to search & browse through the employees' profile and can hire them directly too.
During project posting, employers will also be able to take additional services like featured, an urgent project to have a quick look. Both types of users will also be able to manage their memberships. Other things like support, dispute, escrow, chat, review & rating, showcase projects modules will be there in the system.
Regards,
Saheli
