Hi,
I have read your project but it doesn't give any idea what exactly you need, just adding feature to my ecommerce website doesn't give any idea what you want. So to understand what features you need, you need to explain the features you are looking for so that I can give you exacting timing and price for the project.
I might not have a review on freelancer as I haven't done anything on it, but we are working in software and web development industry since long time.
We can have a good collaboration if will start this project because we are into website designing and development, mobile app designing and development, digital marketing, seo etc. So you will not have to go anywhere with your designing, development and marketing needs.

Pooja Sharma
