1. Build a responsive site similar to Offerup, Letgo, Varagesale, with eCommerce and shipping capabilities like usetrove.com.
2. Need to view on website and phone (android and ios)
3. If you know of a script that I can buy for you to modify, let me know.
>>>>> You must tell me which software or platform offerup, letgo, Varagesale and usestove are built with <<<<<
That will tell me that you are able to build the application I need.
