Hello,
I am an e-commerce site expert and have built several sites similar to your requirement so I am confident to successfully complete your project on time and with a reasonable budget.
I'll integrate order tracking, inventory management and MLM system which are the main ones for your site rest features are also part of your project.
For SMS notification you need to opt for paid SMS service and I'll integrate into the system.
-We'll use Woocommerce platform so you can easily manage site later on.
-For the reward system, we need to clear few things how you want to implement as I have done different types of rewards system as per the client's requirements
-For Android App, you want native or hybrid app the cost will vary on that.
-Which payment gateway you want to use like CCAvenue, Paypal etc?
In the case of a wallet, we can even introduce your own money so it will be easy for your branding as well.
I have many questions so let's discuss further.
Thanks,
Paul
